Yidi Lin e705c39009 libpayload/arch/arm64/mmu: Add CB_MEM_TAG to usedmem_ranges
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.
