Don't enable ordinalCount() or bitCount() for bitset enums

Summary:
Bitfield enums are not sequential, so use of these functions on these enums would be invalid.

I looked at whether we could trivially move `bitCount` to template based on `ordinalCount`. `bitCount` must be constexpr, since we use it directly as a bit-field size constant. `log2` and `ceil` to be constexpr, which isn't here until C++ 26.
