Improve diagnostic on PCRE JIT mmap failure

Print a more informative message that indicates that this is
likely a permission issue, and also indicate that pcre.jit=0
can be used to work around it.

Also automatically disable the JIT, so that this message is
only shown once.

See bug #78630.

Remove checks for locale.h, setlocale, localeconv

The `<loccale.h>` header file, setlocale, and localeconv are part of the
standard C89 [1] and on current systems can be used unconditionally.

Since PHP 7.4 requires at least C89 or greater, the `HAVE_LOCALE_H`,
`HAVE_SETLOCALE`, and `HAVE_LOCALECONV` symbols defined by Autoconf in
configure.ac [2] can be ommitted and simplifed.

The bundled libmagic (file) has also been patched already in version
5.35 and up in upstream location so when it will be patched also in
php-src the check for locale.h header is still left in the configure.ac
and in windows headers definition file.

Remove HAVE_PCRE/HAVE_BUNDLED_PCRE checks

PCRE is always available.

Try to create interned strings in preg_split as well

And convert last_match to last_match_offset, which is more
convenient now.

Cleanup add_offset_pair API

Accept the two offsets directly, rather than doing length calculations
at all callsites. Also extract the logic to create a possibly interned
string.

Switch the split implementation to work on a char* subject internally,
because ZSTR_VAL(subject_str) is a mouthful...

Fix bug #73948

If PREG_UNMATCHED_AS_NULL is used, make sure that unmatched capturing
groups at the end are also set to null, rather than just those in the
middle.
