Fix GH-11160: Few tests failed building with new libxml 2.11.0

It's possible to categorise the failures into 2 categories:
- Changed error message. In this case we either duplicate the test and
modify the error message. Or if the change in error message is
small, we use the EXPECTF matchers to make the test compatible with both
old and new versions of libxml2.
- Missing warnings. This is caused by a change in libxml2 where the
parser started using SAX APIs internally [1]. In this case the
error_type passed to php_libxml_internal_error_handler() changed from
PHP_LIBXML_ERROR to PHP_LIBXML_CTX_WARNING because it internally
started to use the SAX handlers instead of the generic handlers.
However, for the SAX handlers the current input stack is empty, so
nothing is actually printed. I fixed this by falling back to a
regular warning without a filename & line number reference, which
mimicks the old behaviour. Furthermore, this change now also shows
an additional warning in a test which was previously hidden.

Fix #79971: special character is breaking the path in xml function

The libxml based XML functions accepting a filename actually accept
URIs with possibly percent-encoded characters. Percent-encoded NUL
bytes lead to truncation, like non-encoded NUL bytes would. We catch
those, and let the functions fail with a respective warning.

Fix #51903: simplexml_load_file() doesn't use HTTP headers

The `encoding` attribute of the XML declaration is optional; it is good
practice to use external encoding information where available if it is
missing. Thus, we check for `charset` info of `Content-Type` headers,
and see whether the encoding is supported.

We cater to trailing parameters and quoted-strings, but not to escaped
backslashes and quotes in quoted-strings, since no known character
encoding contains these anyway.

Revert "Revert "Merge branch 'PHP-7.4'""

This reverts commit 28e650a, which reverted commit 046dcfb, which had
to be reverted due to phpdbg issues. The culprit was that we did not
properly reset `zend_handler_table` to `NULL`, which is required for
SAPIs which may restart the engine after shutdown.
