The "stub documentation" in `types.rst` does already link to the
in-depth docs in `stdtypes.rst`, but the link isn't obvious for new
users. It deserves to be made more prominent.

Most PRs will require an issue number. Trivial changes, like fixing a
typo, do not need an issue.

The lock is unnecessary as long as there's a GIL, but completely
necessary with a per-interpreter GIL.

Convert day contants to a Day enum, and add a Month enum.

Turns out we always need to remember/restore fstring buffers in all of
the stack of tokenizer modes, cause they might change to
`TOK_REGULAR_MODE` and have newlines inside the braces (which is when we
need to reallocate the buffer and restore the fstring ones).

gh-82814: Adds `errno.EACCES` to the list of ignored errors on
`_copyxattr`.  EPERM and EACCES are different constants but
in general should be treated the same.

This PR makes some minor linting adjustments to the Lib/test module
caught by [ruff](https://github.com/charliermarsh/ruff). The adjustments
are all related to the `F541 f-string without any placeholders` issue.

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.

This PR makes three minor linting adjustments to the `wasm` module
caught by [ruff](https://github.com/charliermarsh/ruff).

Core static types will continue to use the global value.  All other types
will use the per-interpreter value.  They all share the same range, where
the global types use values < 2^16 and each interpreter uses values
higher than that.

This speeds up `super()` (by around 85%, for a simple one-level
`super().meth()` microbenchmark) by avoiding allocation of a new
single-use `super()` object on each use.

Deep-frozen code objects are cannot be shared (currently) by
interpreters, due to how adaptive specialization can modify the
bytecodes. We work around this by only using the deep-frozen objects in
the main interpreter. This does incur a performance penalty for
subinterpreters, which we may be able to resolve later.

This avoids conflicting with the shebang of the called scripts as well
as avoiding hard errors on platforms where the called script runs a
failing unchecked command in the usual course of checking since
