gcc: Make aarch64-mingw32 target install wrap stdint.h

Wrapped stdint.h for AArch64 MinGW32 is useful for bare-matal PE
target e.g. UEFI, as those platform does not provide a system
stdint.h, this would align with x86_64 mingw32 target which provides a
wrapped stdint.h

I have tested this by compiling a AArch64 UEFI Application using gcc's
stdint.h, with -ffreestanding flag, and execute the application with
AAVMF(edk2) inside QEMU.

gcc/ChangeLog:
	* config.gcc (aarch64-*-mingw*): Set use_gcc_stdint to wrap.
