Add sparsebit_for_each_set_range() to allow iterator over a range of set
bits in a range. This will be used by x86 SEV guests to process protected
physical pages (each such page needs to be encrypted _after_ being "added"
to the VM).

Make all sparsebit struct pointers "const" where appropriate. This will
allow adding a bitmap to track protected/encrypted physical memory that
tests can access in a read-only fashion.
