Subject: soc/intel: Refactor ITSS macros

This patch refactors ITSS related SoC specific macros by consolidating
them into a common itss.h file. This improves code maintainability and
reduces redundancy as each SoC previously defined the same macros.

Specific changes include:

- Move SoC specific ITSS macros into intelblocks/itss.h.
- SoC code now includes intelblocks/itss.h instead of the SoC-local
  soc/itss.h.
- Drop soc/itss.h from static ASL files.
- Delete soc/itss.h from all SoC locals except Apollo Lake and
  Sky Lake.

TEST=Able to build and boot google/hatch, google/xol and google/karis.
