gh-93649: Split memory and docstring tests from _testcapimodule.c

• Split up _testcapimodule.c #93649: Split docstring from _testcapimodule.c
• Split up _testcapimodule.c #93649: Splic memory tests from _testcapimodule.c

Should we also add the three tracemalloc tests to Modules/_testcapi/mem.c?

[vstinner]

LGTM.

I suggest to rename "mem.c" to "pymem.c", since most tests are about the "PyMem" API: https://docs.python.org/dev/c-api/memory.html

But I'm also fine with "mem" name, it's up to you.

[erlend-aasland]

I think I prefer the "mem" name, but I'm not sure it matters much really. What do you think about including the tracemalloc tests?

We can add the tracemalloc tests later if we find out they should live in Modules/_testcapi/mem.c

What do you think about including the tracemalloc tests?

Yep, it makes sense to move them in mem.c.
