MdePkg/Base.h: Introduce various alignment-related macros
ALIGNOF: Determining the alignment requirement of data types is
crucial to ensure safe memory accesses when parsing untrusted data.
IS_POW2: Determining whether a value is a power of two is important
to verify whether untrusted values are valid alignment values.
IS_ALIGNED: In combination with ALIGNOF data offsets can be verified.
A more general version of the IS_ALIGNED macro previously defined by
several modules.
ADDRESS_IS_ALIGNED: Variant of IS_ALIGNED for pointers and addresses.
Replaces module-specific definitions throughout the code base.
ALIGN_VALUE_ADDEND: The addend to align up can be used to directly
determine the required offset for data alignment.
