Sync functions checks

Removed unused checks:
- mbsinit check removed, HAVE_MBSINIT removed (not used in php-src)
- mempcpy check removed, HAVE_MEMPCPY removed (not used in php-src anymore since
560ed89bfbb56526251e9bd2fbcb27e5932641d8 which uses PHP's own implementation)
- strpncpy check removed, added via a8c9e893b6911c785f698d724b2ff61e7aebb737 and
not used.
- setpgid check removed since HAVE_SETPGID is not used

Moved to a central configure.ac:
- fpclass
- mbrlen moved to configure.ac (since the HAVE_MBRLEN is used accross the php-src)
- sigprocmask
- getcwd
- getwd
- glob
- strfmon
- nice

Duplicated checks removed:
- gethostname
- getlogin
- getpwuid_r
- socketpair

- mprotect check simplified

Remove HAVE_LIMITS_H check

The limits.h header is part of the C89 and is today available

The timelib has already been patched upstream via
aae5907cb7e775f16bedf61b010b8692c12a2843

PHP extensions out there shouldn't rely on symbols defined during the
build anyway and neither they do on this particular symbol anymore.

Move Autoconf Archive macros to a common m4 dir

Move acinclude.m4 to build/php.m4

The acinclude.m4 file is in a usual Autotools build processed with
Automake's aclocal tool. Since PHP currently doesn't use Automake and
aclocal this file can be moved into the build directory. PHP build
system currently generates a combined aclocal.m4 file that Autoconf
can processes automatically.

However, a newer practice is writing all local macros in separate
dedicated files prefixed with package name, in PHP's case PHP_MACRO_NAME
and putting them in a common `m4` directory. PHP uses currently `build`
directory for this purpose.

Name `php.m4` probably most resembles such file for PHP's case.

PHP manually created the aclocal.m4 file from acinclude.m4 and
build/libtool.m4. Which is also not a particularly good practice [1], so
this patch also removes the generated alocal.m4 usage and uses
m4_include() calls manually in the configure.ac and phpize.m4 files
manually.

- sort order is not important but can be alphabetical
- list of *.m4 files prerequisites for configure script generation
updated
- Moving m4_include() before AC_INIT also removes all comments starting
with hash character (`#`) in the included files.

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.
