Issue:
Return type of twisted.internet.defer._ConcurrencyPrimitive.__aexit__ should be Deferred[Literal[False]]
**Describe the incorrect behavior you saw**

I get lots of mypy errors (error: Missing return statement)  when using DeferredLock 

**Describe how to cause this behavior**

Run mypy on:
```
from twisted.internet.defer import DeferredLock

async def foo() -> int:
    lock = DeferredLock()
    async with lock:
        return 5
```

You'll get : `foo.py:3: error: Missing return statement`

Setting the return type to Literal[False] tells mypy that this context manager doesn't swallow exceptions.

**Additional context**
Add any other context about the problem here.

mypy 0.981 (compiled: yes)
Twisted==22.10.0

Issue:
IReactorProcess.spawnProcess is too strict
Every implementation of `spawnProcess` supplies numerous defaults, but the interface specifies that you have to pass values for everything.

This is particularly a problem because many `Optional` arguments are typed as requiring a value, which makes it impossible to say things like "don't change working directory" or "don't try to `setuid`".

Issue:
twisted.web._flatten._getSlotValue copies slotData on every call.
**Describe the incorrect behavior you saw**

`_getSlotValue` attempts retrieve a value for a named slot from the `slotData` stack by using slice syntax to reverse it and then iterate over it.  

This also causes it create a copy of the list.

In templates with large amounts of data such those used by pydoctor's summary pages.  This copying ends up being a significant amount of time spent generating summary templates.

**Describe how to cause this behavior**

I discovered this issue while running pydoctor under the austin profiler.

I can reproduce it on twisted's own apidocs.

You can view the results of this profiling in speedscope: https://www.speedscope.app/#profileURL=https%3A%2F%2Fgist.githubusercontent.com%2Fdreid%2F197566471f39a96523f5065d19d0bf7f%2Fraw%2F3e7ec92a17bc82d40acceb1e2efcaa3ef7c8ef07%2Ftwisted-austin-trunk.speedscope

In the above profile `_getSlotValue` accounts for ~55s of the total runtime which was 509.42.

**Describe the correct behavior you'd like to see**
`slotData` should not need to be copied on every call to `_getSlotValue` simply to iterate over it in reverse.

Initial profiling using `reversed` instead resulted in reduced runtime to 357.36s

speedscope profile of using reversed is here: https://www.speedscope.app/#profileURL=https%3A%2F%2Fgist.githubusercontent.com%2Fdreid%2F197566471f39a96523f5065d19d0bf7f%2Fraw%2F3e7ec92a17bc82d40acceb1e2efcaa3ef7c8ef07%2Ftwisted-pydoctor-reversed.speedscope

Issue:
twisted.web.template._flattenElement spends a significant amount of runtime in typing.py
**Describe the incorrect behavior you saw**

`_flattenElement` defines a closure `keepGoing` which is used to recursively call `_flattenElement`.  `keepGoing`'s type definition includes multiple `Callable[…]`s.

Since the file does not include `from __future__ import annotations` the type definitions are evaluated at function definition time, which is on every call to `_flattenElement`. 

`typing.Callable.__getitem__` does multiple `isinstance` checks before deferring to the the `@_tp_cache`ed implementation of `Callable.__getitem_inner__`.  This causes evaluating the types for the closure to make up a significant portion of `_flattenElement`'s runtime.

**Describe how to cause this behavior**

This behavior was discovered while profiling the a documentation build using pydoctor under the austin profiler.  

Speedscope URL for the profile is here: https://www.speedscope.app/#profileURL=https%3A%2F%2Fgist.githubusercontent.com%2Fdreid%2F197566471f39a96523f5065d19d0bf7f%2Fraw%2F3e7ec92a17bc82d40acceb1e2efcaa3ef7c8ef07%2Ftwisted-austin-trunk.speedscope

In the profile you can see that the `inner` function in `_tp_cache` accounts for 1m25s of the total runtime, and the `Callable.__getitem__` accounts for 25s of total runtime.
