  [Hexagon] NFC: Reduce the amount of version-specific code (#145812)

There is a lot of redundant code that needs to be modified when new
Hexagon versions are added. Reduce the amount of this redundancy.

- compute ELF flags and attributes based on version feature names;
- simplify EnableHVX option handling by using arch features instead of
arch version enums;
- simplify completeHVXFeatures() by using features;
- delete several unused or redundant functions and constants:
isCPUValid, getCpu, getHexagonCPUSuffix;
- do not set HexagonArchVersion in initializeSubtargetDependencies, it
is set in ParseSubtargetFeatures;
