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
