Sync AC_CHECK_SIZEOF m4 macro calls

Sync AC_CHECK_SIZEOF m4 macro calls

- AC_CHECK_SIZEOF is now called mostly only in PHP_CHECK_STDINT_TYPES()
  macro except for some parts checking for the 32 or 64 bit architecture.
- SIZEOF_CHAR removed since it is always 1
- ZEND_BIN_ID is now of a more logical pattern `BIN_48888` on 64bit
  architectures and `BIN_44444` on 32bit instead of literal string
  `BIN_SIZEOF_CHAR48888` on 64bit and `BIN_SIZEOF_CHAR44444` on 32bit.
  The unneeded SIZEOF_CHAR part has been removed.
- XMLRPC_TYPE_CHECKS removed
- The `long long int` is the same as `long long` and redundant checks
  removed accordingly.
- Removed PHP_CHECK_64BIT macro. Checking if current platform is 64bit
  or not can be also done simply by using a check of the long type on
  place. This removes redundant m4 macro PHP_CHECK_64BIT.
