vc/intel/fsp: Refactor FSP header inclusion for EDK2 compatibility

This change refactors EDK2 essential header management within the FSP
directory to ensure compatibility.

Header selection is now dynamically based on:

* FSP specification version: Distinguishes between 1.1 and 2.x
* EDK2 revision (for FSP 2.x): Chooses the appropriate FSP info header

FSP Header
|
|-> FSP 1.1 specification FSP_INFO_HEADER
|-> FSP 2.0 specification EDK2 release
    |-> EDK2_2017 FSP_INFO_HEADER
    |-> EDK2_2020 FSP_INFO_HEADER
    |-> EDK2_2021 FSP_INFO_HEADER
    |-> EDK2_2023 FSP_INFO_HEADER

Any .C/.H file requires to include FSP_INFO_HEADER can now just add the
FSP header alone.

BUG=b:242829490
TEST=Able to build google/rex0 with 64-bit FSP.
