Boyan Karatotev 9890eab574 fix(brbe): allow RME builds with BRBE
It used to be the case that a FEAT_RME build could not be built with
FEAT_BRBE support. BRBE doesn't have a 3-world aware disable and
MDCR_EL3 was not context switched to allow for disabling in Realm world.

As of commit 123002f917 MDCR_EL3 is
context switched. Since the flag for BRBE support is
ENABLE_BRBE_FOR_NS, move brbe_enable() to only happen for NS world. The
other worlds will see BRBE disabled and branch recording prohibited.
This allows for a build with both RME and BRBE.

Note that EL2 BRBE registers are not context switched. Further work is
needed if non-NS support is required.
