[UCRT] Add GCC compatible definition of _CRT_STDIO_INLINE
In C99 mode GCC emits global symbols for inline functions, as soon as the
compilation unit contains a declaration that marks the function as "extern". A
number of functions like printf are implicitly declared as extern by GCC, which
seemingly cannot be disabled. This would lead to the inline function being
emitted as a global symbol in every compilation unit. Using static inline
prevents duplicate symbol errors.
