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().
