mesa: Permanently enable features supported by target CPU at compile time.
This will remove the need for unnecessary runtime checks for CPU features if
already supported by target CPU, resulting in smaller and less branchy code.
V2:
- Removed the SSSE3 related part for the not yet merged patch.
- Avoiding redefinition of macros.
