This fixes several ways file descriptors could be leaked from `subprocess.Popen` constructor during error conditions by opening them later and using a context manager "fds to close" registration scheme to ensure they get closed before returning.

Fix Zip64 extensions not being properly applied in some cases:
Fixes an issue where adding a small file to a `ZipFile`
object while forcing zip64 extensions causes an extra Zip64 record to be
added to the zip, but doesn't update the `min_version` or file sizes in
the primary central directory header.
Also fixed an edge case in checking if zip64 extensions are required:
This fixes an issue where if data requiring zip64 extensions was added
to an unseekable stream without specifying `force_zip64=True`, zip64
extensions would not be used and a RuntimeError would not be raised when
closing the file (even though the size would be known at that point).
This would result in successfully writing corrupt zip files.
Deciding if zip64 extensions are required outside of the `FileHeader`
function means that both `FileHeader` and `_ZipWriteFile` will always be
in sync. Previously, the `FileHeader` function could enable zip64
extensions without propagating that decision to the `_ZipWriteFile`
class, which would then not correctly write the data descriptor record
or check for errors on close.
If anyone is actually using `ZipInfo.FileHeader` as a public API without
explicitly passing True or False in for zip64, their own code may still be
susceptible to that kind of bug unless they make a similar change to
where the zip64 decision happens.
Fixes#103861

Add http.client.HTTPConnection method get_proxy_response_headers() - this is a followup to https://github.com/python/cpython/pull/26152 which added it as a non-public attribute. This way we don't pre-compute a headers dictionary that most users will never access. The new method is properly public and documented and triggers full proxy header parsing into a dict only when actually called.

This implements PEP 695, Type Parameter Syntax. It adds support for:
- Generic functions (def func[T](): ...)
- Generic classes (class X[T](): ...)
- Type aliases (type X = ...)
- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules

When preparing the _io extension module for isolation, many methods were
adapted to Argument Clinic. Some of these used the '*args: object'
signature, which is incorrect. These are now corrected to an exact
signature, and marked unused, since they are stub methods.
* Add basic mypy workflow to CI
* Make the type check pass

By convention make targets that don't refer to a file have a dependency
on the fake .PHONY target/file. This ensures that these targets are
always evaluated because there is no rule to create a .PHONY file
and that will force make to think the rule is out of date and needs
to be rebuilt.
This commit consistently associates virtual targets with .PHONY by
declaring the .PHONY dependency immediately above the make rule. This
should avoid race conditions and avoidable rebuilds across multiple make
invocations.
* Pickle the `name` and `args` attributes of AttributeError when present.
