Issue:
[BUG] `IS_UNSIGNED()` macro is applied to `const` types in test suite
### Describe the bug

Example (there are several such modules):
```
Compiler output for module memslice:
memslice.cpp:1348:37: warning: type qualifiers ignored on cast result type [-Wignored-qualifiers]
 #define IS_UNSIGNED(type) (((type) -1) > 0)
                                     ^
memslice.cpp:4250:104: note: in expansion of macro ‘IS_UNSIGNED’
 static __Pyx_TypeInfo __Pyx_TypeInfo_int__const__ = { "const int", NULL, sizeof(int const ), { 0 }, 0, IS_UNSIGNED(int const ) ? 'U' : 'I', IS_UNSIGNED(int const ), 0 };
```
We should strip off the `const`, if possible. It leads to the above warning in C++.

Issue:
PyTypeObject fields on PyPy are not consistent with CPython
### Describe your issue

I have been trying to get cython to handle the differences in `PyTypeObject` between the different PyPy versions, but there are still `-Wmissing-field-initializers` warnings. The various attempts were #4509, #4517. Currently the problem is the `tp_print` field, which was removed for CPython3.9. It is still there in PyPy3.9. PyPy3.10 removed both the `tp_print` field and the `tp_pypy_flags` field, so finally the struct is similar to the CPython3.10 one.

I thought I could sidestep the problem in #5435 by using designated initializers. That PR is still not passing CI, and @scoder recommended merging it only for 3.1 since it requires C99 compilers. 

<details><summary>status of C99 designated initializers in various compilers</summary>

FWIW, gcc has [supported designated initializers since v3.0](https://gcc.gnu.org/c99status.html) (about half-way down the page) and MSVC supports them since VS 2019 16.1](https://learn.microsoft.com/en-us/cpp/overview/visual-cpp-language-conformance?view=msvc-170). Clang does [not list a version number](https://clang.llvm.org/c_status.html) for support of the feature. 

</details>

So I am left with adding yet another preprocessor macro around the `tp_print` field in `PyTypeObject`. Maybe I should collapse the multiple duplicate long conditional expressions into a `CYTHON_HAS_TP_PRINT` macro.

Issue:
[BUG] vector[bint] causes odd behaviour in vector[int]
### Describe the bug

I found some undesired behaviour while using the C++ vector class. A specific inclusion of a `bint` variable causes other `int`s to become `bint`s.

This code
```cython
%%cython -a --cplus
from libcpp.vector cimport vector
print(<vector[int]>range(10))
```
outputs
`[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]`
which is expected.

But this code
```cython
%%cython -a --cplus
from libcpp.vector cimport vector
cdef vector[bint] foobar = []
print(<vector[int]>range(10))
```
outputs
`[0, 1, 1, 1, 1, 1, 1, 1, 1, 1]`
which is very unexpected

I think something is wrong here.

### Code to reproduce the behaviour:

```cython
from libcpp.vector cimport vector
cdef vector[bint] foobar = []
print(<vector[int]>range(10))
```


### Expected behaviour

`<vector[int]>range(10)` should be a vector with elements `[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]`, but it produces a vector of `bint` instead.

Issue:
[BUG] enum class initializer throws NameError
### Describe the bug

In C++ initialization of an enum class should value initialize (at least in the case of an empty initializer list, I haven't dug too deeply into what should happen if given a real value). Cython compiles such code but then throws a NameError at runtime.

### Code to reproduce the behaviour:

```cython
# distutils: language = c++


cdef enum class my_enum(int):
    a = 1
    b = 2


def f():
    my_enum()
```

This code compiles correctly, but at runtime I get:
```
(main) dt08% python -c 'import definitions; definitions.f()'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "definitions.pyx", line 10, in definitions.f
    my_enum()
NameError: name 'my_enum' is not defined
```


### Expected behaviour

 I think throwing an error during compilation would be an acceptable outcome here, if normal value initialization is not possible (especially if the non-empty initializer list case is actually UB; I haven't looked deeply enough yet to say either way).

Issue:
TESTING: what should happen with limited API tests and PyPy?
### Describe your issue

What should be the approach to limited API testing and PyPy? It does not support the limited API, so any tests that use `-DCYTHON_LIMITED_API=1` (like `tests/run/isolated_limited_api_tests.srctree`) will not work. A few choices:
- add the specific limited-API tests to the `tests/pypy_bugs.txt`. What will happen as more and more tests are converted to use the limited-API?
- undefine `CYTHON_LIMITED_API` for PyPy, then PyPy will run the test as if it does not limit the API
- skip the limited-API-specific tests in the [runtests.py lambda](https://github.com/cython/cython/blob/1cde6233a58538c146a16adcb38496c8e81b0b78/runtests.py#L509) for PyPy.


Discussion:
We should add a tag "limitedapi" to the tests specific to that API and exclude all tests with that tag on PyPy (and other Pythons that don't support it). Basically, whenever the `--limited-api` option is not passed to the test runner, they should be excluded.
Note also that we're not intending to add a lot of special tests for the Limited API. The one(s?) that we have are rather because we need to test *something* and most things still don't work, so including specific tests is still easier than excluding all but some.

Instructions on how to install Cython without compilation in project description are outdated
### Describe your issue

The project description displayed on PyPI reports that Cython can be installed avoiding compilation running
```
pip install Cython --install-option="--no-cython-compile"
```
however, `pip` since version does not accept the `--install-option` anymore.

Even when it did, I believe that the option name was `--install-options`.

Issue:
[BUG] Limited API: cythonize() method drops py_limited_api=True 
### Describe the bug

In a setup.py file, if you use an explicit setuptools Extension with `py_limited_api=True`, then pass this to the cythonize() method, the resulting .so files incorrectly include a `.cpython-38-x86_64-linux-gnu.so` suffix (or similar), whereas the expected suffix is `.abi3.so`. 

As far as I can tell, this is because the `py_limitd_api` field is popped from the kwarg blob by setuptools [here](https://github.com/pypa/setuptools/blob/main/setuptools/extension.py#L129), and as a result when cython attempts to create a new Extension object [here](https://github.com/cython/cython/blob/d455d51bf31379f47c074e40517e24857d4d9cc0/Cython/Build/Dependencies.py#L866) the field isn't included. It kinda looks like the fix is probably to differentiate between *Extension_distutils* and *Extension_setuptools* and in the latter case read *py_limitd_api*.

The issue can be worked around by explicitly using Cython.Distutils.extension.Extension.

Discussion:
We can probably just always look up that attribute and if it exists, copy its value to the newly created Extension instances. PR welcome.
