gh-101659: Isolate "obmalloc" State to Each Interpreter (gh-101660)
This is strictly about moving the "obmalloc" runtime state from
`_PyRuntimeState` to `PyInterpreterState`.  Doing so improves isolation
between interpreters, specifically most of the memory (incl. objects)
allocated for each interpreter's use.  This is important for a
per-interpreter GIL, but such isolation is valuable even without it.

FWIW, a per-interpreter obmalloc is the proverbial
canary-in-the-coalmine when it comes to the isolation of objects between
interpreters.  Any object that leaks (unintentionally) to another
interpreter is highly likely to cause a crash (on debug builds at
least).  That's a useful thing to know, relative to interpreter
isolation.

gh-102304: Move _Py_RefTotal to _PyRuntimeState (gh-102543)
The essentially eliminates the global variable, with the associated benefits. This is also a precursor to isolating this bit of state to PyInterpreterState.

Folks that currently read _Py_RefTotal directly would have to start using _Py_GetGlobalRefTotal() instead.

Exclude `ceval.c` from the C-analyzer tool (#102735)
The "check if generated files are up to date" CI check appears to be currently failing on all PRs (but not on pushes to main) 

See, for example:
- https://github.com/python/cpython/pull/94468
- https://github.com/python/cpython/pull/94468
- https://github.com/python/cpython/pull/102731

This appears to be because the C-analyzer tool doesn't like the `#line` directives introduced in 70185de1ab. I'm advised by the message printed to the terminal in https://github.com/python/cpython/actions/runs/4428706945/jobs/7768216988#step:14:84 that this is the appropriate short-term fix!

gh-81057: Add a CI Check for New Unsupported C Global Variables (gh-102506)
This will keep us from adding new unsupported (i.e. non-const) C global variables, which would break interpreter isolation.

FYI, historically it is very uncommon for new global variables to get added. Furthermore, it is rare for new code to break the c-analyzer. So the check should almost always pass unnoticed.

Note that I've removed test_check_c_globals. A test wasn't a great fit conceptually and was super slow on debug builds. A CI check is a better fit.

This also resolves gh-100237.

gh-81057: Vendor a Subset of distutils for the c-analyzer Tool (gh-102505)
distutils was removed in November. However, the c-analyzer relies on it. To solve that here, we vendor the parts the tool needs so it can be run against 3.12+. (Also see gh-92584.)

Note that we may end up removing this code later in favor of a solution in common with the peg_generator tool (which also relies on distutils).  At the least, the copy here makes sure the c-analyzer tool works on 3.12+ in the meantime.

gh-90110: Fix the c-analyzer Tool (#102483)
Some incompatible changes had gone in, and the "ignore" lists weren't properly undated. This change fixes that. It's necessary prior to enabling test_check_c_globals, which I hope to do soon.

Note that this does include moving last_resort_memory_error to PyInterpreterState.

(If PEP 684 is accepted then we will follow up by moving them all to PyInterpreterState.)
