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.

gh-84570: Implement Waiting in SendChannel.send() (gh-110565) 
We had been faking it (poorly).

We will add timeouts separately.

gh-101524: Split Up the _xxsubinterpreters Module (gh-101526) 
This is step 1 in potentially dropping all the "channel"-related code. Channels have already been removed from PEP 554.
