\brief Return the alignment of a type in bytes as per C++expr.alignof
standard.
If the type declaration is invalid, CXTypeLayoutError_Invalid is returned.
If the type declaration is an incomplete type, CXTypeLayoutError_Incomplete
is returned.
If the type declaration is a dependent type, CXTypeLayoutError_Dependent is
returned.
If the type declaration is not a constant size type,
CXTypeLayoutError_NotConstantSize is returned.
