Issue:
[bug] `cmake.test()` cannot execute
### Environment Details (include every applicable attribute)
  * Operating System+version: Ubuntu 22.04 on WSL
  * Compiler+version: CMake 3.23.1
  * Conan version: 1.49.0
  * Python version: 3.10.4

### Steps to reproduce (Include if Applicable)

Put `cmake.test()` and run `conan build .` with `Ninja Multi-Config` as a generator.

### Logs (Executed commands with output) (Include/Attach if Applicable)

```

```

CMake target `RUN_TESTS` is not available. `test` target works correctly but Conan does not use it for some reason.


Discussion:
Yes, sounds that the test target is not taking into account ``Ninja Multi-Config`` generator. Seems the fix could be easy.
