General: Mark file-scope constexpr variables as inline 

Allows the compiler to unify all usages of these constants down to a
single address if they're ODR used, rather than creating an individual
copy within each translation unit.

Unfortunately all file-scope variables don't have inline implied for
them by default (only for static class member variables).

Shrinks the size of the emitted binary a little bit.
