MdePkg/Include: Add enumeration size checks to Base.h 

https://bugzilla.tianocore.org/show_bug.cgi?id=181

Add size check for 8-bit, 16-bit, and 32-bit enums
to make sure they follow the UEFI Specification 2.3.1
Data Types.

<Enumerated Type>

Element of a standard ANSI C enum type declaration.
Type INT32.or UINT32.  ANSI C does not define the
size of sign of an enum so they should never be
used in structures. ANSI C integer promotion rules
make INT32 or UINT32 interchangeable when passed as
an argument to a function.
