Fix #79922: Crash after multiple calls to xml_parser_free()

We must not call `zend_list_delete()` in resource closer functions
exposed to userland, because decreasing the refcount there leads to
use-after-free scenarios. In this case, commit 4a42fbb worked for
typical use-cases where `xml_parser_free()` has been called exactly
once for the resource, because there is an internal zval (`->index`)
referencing the same resource which already increased the refcount by
one. However, when `xml_parser_free()` is called multiple times on the
same XML parser resource, the resource would be freed prematurely.

Instead we forcefully close the resource in `xml_parser_free()`. We
also could decrease the refcount of the resource there, but that would
require to call `xml_parser_free()` which is somewhat uncommon, and
would be particularly bad wrt. PHP 8 where that function is a NOP, and
as such doesn't have to be called. So we do no longer increase the
refcount of the resource when copying it to the internal zval, and let
the usualy refcounting semantics take care of the resource destruction.

Fix #79877: getimagesize function silently truncates after a null byte

We have to check for NUL bytes if `getimagesize()` has been called.

Fix #79797: Use of freed hash key in the phar_parse_zipfile function

We must not use heap memory after we freed it.

Fix #79919: Stack use-after-scope in define()

Instead of the temporary `rv`, we use the `val_free` which is there for
this purpose.

Amendment to OPcache base file removal

We fix the erroneous segment size. We also keep the segment pointer at
the allocated address, but increase the position instead.

Consider op1 literal of FETCH_OBJ_R

FETCH_OBJ_R may have an op1 CONST operand, even though it will
always error. We should take this into account when compacting
literals.
