RFR: 8377507: Store cpu features in AOTCodeCache

[Ashutosh Mehra]

This PR adds the ability to cache and validate cpu features in the AOTCodeCache. It adds new APIs to `Abstract_VM_Version` to facilitate retrieval, storage and validation of cpu features between assembly phase and production run. Default implementation of these APIs is no-op. Each platform that supports AOTCodeCache can implement these APIs in the arch-specific `VM_Version` class.
This patch follows the Leyden premain implementation. It allows the cpu feature set of the production run to be a super-set of that of the assembly phase. This may change in future if we decide to that the cpu feature set should be the exact match.
