Introduce ZEND_EXTENSION() to the Windows build system

Zend Extensions should now be declared in their config.w32 with a ZEND_EXTENSION() call instead of EXTENSION(), the parameters sent is identical.

For a cross version compatible config.w32, the following will do:
if (typeof(ZEND_EXTENSION) == 'undefined') {
  EXTENSION(...);
} else {
  ZEND_EXTENSION(...);
}
