Fixed bug #79946

Declare __STDC_CONSTANT_MACROS and __STDC_FORMAT_MACROS via -D
to make sure they are declared before the first stdint.h include.
We also define these in php_stdint.h, but don't always include that
file first.

This is necessary for old compilers that use C99 rather than C11
semantics for stdint.h.
