Brad King 194b74daec XL: Fix C default level detection when invoked as 'cc' ...

The IBM XL C compiler does not define `__STDC__` when invoked as plain
`cc` instead of `xlc`, so `CMAKE_C_STANDARD_COMPUTED_DEFAULT` does not
get set and CMake fails.  Teach CMake about the XL compiler's default C
standard in this case.

Fixes: #17649
