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.

-If the platform port uses the Activity Monitor Unit, the following constant
-may be defined:

-- **PLAT_AMU_GROUP1_COUNTERS_MASK**
- This mask reflects the set of group counters that should be enabled. The
- maximum number of group 1 counters supported by AMUv1 is 16 so the mask
- can be at most 0xffff. If the platform does not define this mask, no group 1
- counters are enabled.
