to the main block.

mem-cache: Optimize sector valid and secure check

Previously a loop was being done to check whether the
block was valid/secure or not. Variables have been
added to skip this loop and save and update sector
block state when sub-blocks are validated, invalidated
and secured.

mem-cache: Move sector_blks to tags folder

Move sector_blks.hh and sector_blks.cc to the tags folder,
as its usage scope is restricted to the tags, and caches
should not be aware of them.
