VideoCommon/IndexGenerator: Make use of if constexpr

Browse Source 
We can use if constexpr with the template functions that pass in a
non-type template parameter, allowing the removal of branches that
aren't taken at compile time.

Compilers will generally do this by default, however, we now give a
gentle prodding to the compiler if this would otherwise not be the case.
