refactor(amu): separate the EL2 and EL3 enablement code

Combining the EL2 and EL3 enablement code necessitates that it must be
called at el3_exit, which is the only place with enough context to make
the decision of what needs to be set.
Decouple them to allow them to be called from elsewhere. Also take
some time to clarify and simplify AMU code.

The sanity check in the context_restore() is now wrong, as the cpu may
turn off on suspend, thus resetting the value of the counter enables.
Remove it.

Finally, this completes the migration to cm_manage_extensions_el3() and
manage_extensions_nonsecure() so manage_extensions_nonsecure_mixed() is
being removed.
