Disable global state test on Windows

It looks like the config.w32 uses CHECK_HEADER_ADD_INCLUDE to add the include
path to libxml into the search path.
That doesn't happen in zend-test.
To add to the Windows trouble, libxml is statically linked in, ext/libxml can
only be built statically but ext/zend-test can be built both statically and
dynamically.
So the regression tests won't work in all possible configurations anyway on Windows.
All of this is no problem on Linux because it just uses dynamic linking
and pkg-config, without any magic.

Sanitize libxml2 globals before parsing

Fixes GHSA-3qrf-m4j2-pcrr.

To parse a document with libxml2, you first need to create a parsing context.
The parsing context contains parsing options (e.g. XML_NOENT to substitute
entities) that the application (in this case PHP) can set.
Unfortunately, libxml2 also supports providing default set options.
For example, if you call xmlSubstituteEntitiesDefault(1) then the XML_NOENT
option will be added to the parsing options every time you create a parsing
context **even if the application never requested XML_NOENT**.

Third party extensions can override these globals, in particular the
substitute entity global. This causes entity substitution to be
unexpectedly active.

Fix it by setting the parsing options to a sane known value.
For API calls that depend on global state we introduce
PHP_LIBXML_SANITIZE_GLOBALS() and PHP_LIBXML_RESTORE_GLOBALS().
For other APIs that work directly with a context we introduce
php_libxml_sanitize_parse_ctxt_options().

Stop closing stderr and stdout streams (#8569)

Extensions may (and do) write to stderr in mshutdown and similar. In
the best case, with the stderr stream closed, it's just swallowed.

However, some libraries will do things like try to detect color, and
these will outright fail and cause an error path to be taken.

Fix #81435 Observer current_observed_frame may point to an old (overwritten) frame

Ensure current_observed_frame always points to an actually observed frame.
This solution has a caveat of being O(stack size), with the worst case occurring if there are a lot of frames between the current and previous observed frames.
An O(1) solution would require keeping track of the previous observed frame, which would require some additional frame attached metadata, which is best not attempted in an already released version.

Pass zend_execute_data instead of zend_function to fcall init

The motivation for this change is to prevent extensions from having to check executor globals for the current execute_data during function call init. A previous implementation of the observer API initialized the function call from runtime cache initialization before execute_data was allocated which is why zend_function was passed in.

But now that the observer API is implemented via opcode specialization, it makes sense to pass in the execute_data. This also keeps the API a bit more consistent for existing extensions that already hook zend_execute_ex.

Closes GH-6209
