Remove Z_PARAM separate params where they don't make sense

Separation can only possibly make sense for array parameters
(or something that can contain arrays, like zval parameters). It
never makes sense to separate a bool.

The deref parameters are also of dubious utility, but leaving them
for now.

They will now follow the canonical order of types. Older macros are

Allocate temporary PCRE match data using ZMM

Create a separate general context that uses ZMM as allocator and
use it to allocate temporary PCRE match data (there is still one
global match data). There is no requirement that the match data
and the compiled regex / match context use the same general context.

This makes sure that we do not leak persistent memory on bailout
and fixes oss-fuzz #25296, on which half the libfuzzer runs
currently get stuck.

Implement named parameters

From an engine perspective, named parameters mainly add three

Implement named parameters

From an engine perspective, named parameters mainly add three
concepts:

* The SEND_* opcodes now accept a CONST op2, which is the
argument name. For now, it is looked up by linear scan and
runtime cached.
* This may leave UNDEF arguments on the stack. To avoid having
to deal with them in other places, a CHECK_UNDEF_ARGS opcode
is used to either replace them with defaults, or error.
* For variadic functions, EX(extra_named_params) are collected
and need to be freed based on ZEND_CALL_HAS_EXTRA_NAMED_PARAMS.

Ensure ctype_string is NULL for C locale

We already document that this is the case, but currently it's only
true if setlocale() has not been called. Make sure ctype_string is
always NULL, even with an explicit "C" locale call, so we can
more efficiently check whether we are in the "C" locale.
