Remove LIBZEND_CHECK_INT_TYPE and PHP_CHECK_TYPES

Checking for int32_t and uint32_t types is already done by the
PHP_CHECK_STDINT_TYPES m4 macro.

The PHP_CHECK_TYPES m4 macro has been once used by the mysqlnd and has
been removed via 14caf17 and
additionally, the internal unused macro _PHP_DEF_HAVE_FILE has been
removed.

Additionally, the unused PHP_HAVE_STDINT_TYPES symbol has been removed.
