Subject: [PATCH 1/1] BaseTools: use stdint.h for GCC ProcessorBind.h typedefs

The AArch64 definitions of UINT64/INT64 differ from the X64 ones.
Since this is on the tool side, doing like X64 and picking the definitions from stdint.h feels like a better idea than hardcoding them. So copy the pattern from X64/ProcesorBind.h.

This was triggered by one of the Risc-V patches which may need to end up being modified to the point where this issue goes away, but the current situation seems suboptimal. (Do you use %llx or %lx to print an Elf64_Addr on a 64-bit LP architecture?)
