refactor(amu)!: privatize unused AMU APIs
This change reduces the exposed surface area of the AMU API in order to
simplify the refactoring work in following patches. The functions and
definitions privatized by this change are not used by other parts of the
code-base today.
BREAKING CHANGE: The public AMU API has been reduced to enablement only
to facilitate refactoring work. These APIs were not previously used.

refactor(amu)!: remove `PLAT_AMU_GROUP1_COUNTERS_MASK`
With the introduction of MPMM, the auxiliary AMU counter logic requires
refactoring to move away from a single platform-defined group 1 counter
mask in order to support microarchitectural (per-core) group 1 counters.
BREAKING CHANGE: The `PLAT_AMU_GROUP1_COUNTERS_MASK` platform definition
has been removed. Platforms should specify per-core AMU counter masks
via FCONF or a platform-specific mechanism going forward.

refactor(gpt): productize and refactor GPT library
This patch updates and refactors the GPT library and fixes bugs.
- Support all combinations of PGS, PPS, and L0GPTSZ parameters.
- PPS and PGS are set at runtime, L0GPTSZ is read from GPCCR_EL3.
- Use compiler definitions to simplify code.
- Renaming functions to better suit intended uses.
- MMU enabled before GPT APIs called.
- Add comments to make function usage more clear in GPT library.
- Added _rme suffix to file names to differentiate better from the
GPT file system code.
- Renamed gpt_defs.h to gpt_rme_private.h to better separate private
and public code.
- Renamed gpt_core.c to gpt_rme.c to better conform to TF-A precedent.

The workaround is to write the value 2'b11 to the PF_MODE bits
