gh-136421: Load `_datetime` static types during interpreter initialization (GH-136583)
`_datetime` is a special module, because it's the only non-builtin C extension that contains static types. As such, it would initialize static types in the module's execution function, which can run concurrently. Since static type initialization is not thread-safe, this caused crashes. This fixes it by moving the initialization of `_datetime`'s static types to interpreter startup (where all other static types are initialized), which is already properly protected through other locks.

As noted in the new tests, there are a few situations we must carefully accommodate
for functions that get pickled during interp.call(). We do so by running the script
from the main interpreter's __main__ module in a hidden module in the other
interpreter. That hidden module is used as the function __globals__.

* make a couple of typedefs opaque
* decouple errors from session state
* improve tracebacks for propagated exceptions
This change helps simplify several upcoming changes.

doing so is the SC condition under which the module can land in 3.14.)

* gh-91048: Reorder result tuple of parse_code_object (GH-134898)
Reorder result tuple of parse_code_object
The standard followed by APIs like pstat.Stats is to take a file, line,
function triplet. The parse_code_object function (and callers exposing
this in Python like RemoteUnwinder.get_stack_trace) return function,
file, line triplets which requires the caller to reorder these when
using it in classes like pstat.Stats.
