CB_MEM_TAG is considered as an reserved memory. But we want to mange this region in the payload and release this region when MTE is inactive. Add CB_MEM_TAG memory range to usedmem_ranges to get a page table mapping and mark it as used. BUG=b:438666196,b:474306129 TEST=Check the tag region is wiped out in DEV mode.
