refactor(amu): conditionally compile auxiliary counter support

This change reduces preprocessor dependencies on the
`AMU_GROUP1_NR_COUNTERS` and `AMU_GROUP1_COUNTERS_MASK` definitions, as
these values will eventually be discovered dynamically.

In their stead, we introduce the `ENABLE_AMU_AUXILIARY_COUNTERS` build
option, which will enable support for dynamically detecting and
enabling auxiliary AMU counters.

This substantially reduces the amount of memory used by platforms that
know ahead of time that they do not have any auxiliary AMU counters.
