Remove PHP atomic includes and PHP_DEFINE M4 macro (#13372)

PHP_DEFINE was introduced with the PHP 5 build system
9d9d39a0de3bec962c343051011f5a2ed7d7b242 and then refactored via
350de12bc24472ccf20ff9a8b39a6da0185c070d.

This was once used to put defined constants into a single file to have
more fine-graned dependencies (atomic includes). Since no known PHP
extension is using this and it makes very little sense to use this, this
M4 macro can be removed in favor of the Autoconf native way using
AC_DEFINE and the usual included files php_config.h and config.h.

- Generated unused include directory removed
- Remove include dir from DEFS
- Remove also include dir from PDO checks

SunOS 4.1.4 from 1994 didn't have fclose declared in standard header

the C89+ standard and declaration is present on Solaris 10 (SunOS 5.10)
and later.

Remove obsolescent AC_TYPE_SIZE_T (#12719)

The macro checks for existence of size_t in <stddef.h> otherwise it sets
it to 'unsigned int'. The size_t is part of C89 standard and all
platforms should have it. Macro is also marked to be made obsolete in
the future versions of Autoconf.

At this point there is still AC_FUNC_ALLOCA in PHP's configure.ac which
uses AC_TYPE_SIZE_T under the hood so the check is still done there in
the meantime.
