feat(brbe): add BRBE support for NS world

This patch enables access to the branch record buffer control registers
in non-secure EL2 and EL1 using the new build option ENABLE_BRBE_FOR_NS.
It is disabled for all secure world, and cannot be used with ENABLE_RME.

This option is disabled by default, however, the FVP platform makefile
enables it for FVP builds.
