[efi] Skip including the EDK2 ProcessorBind.h header for 32-bit RISC-V

Browse Source 
We currently include the EDK2 RiscV64/ProcessorBind.h header when
building for 32-bit RISC-V, as a placeholder since there is no support
for 32-bit RISC-V in upstream EDK2.

This causes errors when attempting to use the EDK2 VA_START() et al
macros, since RiscV64/ProcessorBind.h ends up defining UINTN with a
size different from the size of a pointer.

Fix by falling back to the generic definitions for UINTN etc (as used
for EFI_HOSTONLY) whenever we don't have an architecture-specific
ProcessorBind.h header available.
