gh-112287: Speed up Tier 2 (uop) interpreter a little (#112286)
This makes the Tier 2 interpreter a little faster.
I calculated by about 3%,
though I hesitate to claim an exact number.

This starts by doubling the trace size limit (to 512),
making it more likely that loops fit in a trace.

The rest of the approach is to only load
`oparg` and `operand` in cases that use them.
The code generator know when these are used.

For `oparg`, it will conditionally emit
```
oparg = CURRENT_OPARG();
```
at the top of the case block.
(The `oparg` variable may be referenced multiple times
by the instructions code block, so it must be in a variable.)

For `operand`, it will use `CURRENT_OPERAND()` directly
instead of referencing the `operand` variable,
which no longer exists.
(There is only one place where this will be used.)

gh-106529: Make FOR_ITER a viable uop (#112134)
This uses the new mechanism whereby certain uops
are replaced by others during translation,
using the `_PyUop_Replacements` table.
We further special-case the `_FOR_ITER_TIER_TWO` uop
to update the deoptimization target to point
just past the corresponding `END_FOR` opcode.

Two tiny code cleanups are also part of this PR.

gh-111569: Fix critical sections test on WebAssembly (GH-111897)
This adds a macro `Py_CAN_START_THREADS` that corresponds to the Python
function `test.support.threading_helper.can_start_thread()`. WASI and
some Emscripten builds do not have a working pthread implementation.

This macro is used to guard the critical sections C API tests that
require a working threads implementation.

gh-111569: Implement Python critical section API (gh-111571)
Critical sections are helpers to replace the global interpreter lock
with finer grained locking.  They provide similar guarantees to the GIL
and avoid the deadlock risk that plain locking involves.  Critical
sections are implicitly ended whenever the GIL would be released.  They
are resumed when the GIL would be acquired.  Nested critical sections
behave as if the sections were interleaved.

gh-76785: Move _Py_excinfo Functions Out of the Internal C-API (gh-111715)
I added _Py_excinfo to the internal API (and added its functions in Python/errors.c) in gh-111530 (9322ce9).  Since then I've had a nagging sense that I should have added the type and functions in its own PR.  While I do plan on using _Py_excinfo outside crossinterp.c very soon (see gh-111572/gh-111573), I'd still feel more comfortable if the _Py_excinfo stuff went in as its own PR.  Hence, here we are.

(FWIW, I may combine that with gh-111572, which I may, in turn, combine with gh-111573.  We'll see.)

gh-76785: Crossinterp utils additions (gh-111530)
This moves several general internal APIs out of _xxsubinterpretersmodule.c and into the new Python/crossinterp.c (and the corresponding internal headers).

Specifically:

* _Py_excinfo, etc.:  the initial implementation for non-object exception snapshots (in pycore_pyerrors.h and Python/errors.c)
* _PyXI_exception_info, etc.:  helpers for passing an exception beween interpreters (wraps _Py_excinfo)
* _PyXI_namespace, etc.:  helpers for copying a dict of attrs between interpreters
* _PyXI_Enter(), _PyXI_Exit():  functions that abstract out the transitions between one interpreter and a second that will do some work temporarily

Again, these were all abstracted out of _xxsubinterpretersmodule.c as generalizations.  I plan on proposing these as public API at some point.
