Remove HAVE_STDARG_H

Browse Source 
The C89 standard and later defines the `<stdarg.h>` header as part of
the standard headers [1]. On current systems it is always present and
can be included unconditionally.

Checking for presence and functionality of the `<stdarg.h>` header and
variadic function is not relevant anymore on current systems since this
is always available.

Also Autoconf suggests relying on at least C89 or above [2] and [3].

The following files were regenerated with re2c 1.0.3:
- Zend/zend_language_scanner.c
- Zend/zend_language_scanner_defs.h
