ArmPkg: update InvalidateInstructionCacheRange to flush only to PoU
This patch updates the ArmPkg variant of InvalidateInstructionCacheRange to
flush the data cache only to the point of unification (PoU). This improves
performance and also allows invalidation in scenarios where it would be
inappropriate to flush to the point of coherency (like when executing code
from L2 configured as cache-as-ram).

ArmPkg: ArmLib: purge incorrect ArmDrainWriteBuffer () alias
In ArmLib, there exists an alias for ArmDataSynchronizationBarrier,
named after one of several names for the pre-ARMv6 cp15 operation that
was formalised into the Data Synchronization Barrier in ARMv6.
This alias is also the one called from within ArmLib, in preference of
the correct name. Through the power of code reuse, this name slipped
into the AArch64 variant as well.
Expunge it from the codebase.

ArmPkg/ArmLib: move cache maintenance sync barriers out of loop
There is no need to issue a full data synchronization barrier and an
instruction synchronization barrier after each and every set/way or
MVA cache maintenance operation. For the set/way case, we can simply
remove them, since the set/way outer loop already issues the required
barriers after completing its traversal over all the cache levels.
For the MVA case, move the data synchronization barrier out of the
loop, and add the instruction synchronization barrier to the I-cache
invalidation by MVA routine.
