With the introduction of the use of _Static_assert, edk2 requires a C11
compatible compiler. Update Include/Base.h to be compliant with C11.
As of C11, the maximum type of an enum is type `int`. Since the UEFI
Specification 2.3.1 Errata C allows either `int` or `unsigned int`, fix
the 32-bit enum check to use a signed int.
Since the UEFI 2.3 Specification only allowed signed int, update the
comment to reference 2.3.1 Errata C where the change was made to allow
unsigned int.
