[PGO] Make indexed value profile data more compact
- Make indexed value profile data more compact by peeling out
the per-site value count field into its own smaller sized array.
- Introduced formal data structure definitions to specify value
profile data layout in indexed format. Previously the layout
of the data is only assumed in the client code (scattered in
three different places : size computation, EmitData, and ReadData
- The new data structure serves as a central place for layout documentation.
- Add interfaces to force BE output for value profile data (testing purpose)
- Add byte swap unit tests
