Replace const fn name() with associated NAME constants (#715)

`CStr::from_bytes_with_nul_unchecked` is `const`-stable since Rust 1.59
which is already required for `ash` so it is high time to finally turn
these inlined `name()` functions into associated constants (which is a
breaking change in itself that cannot be backported).
