Support (boot) partition preloading. 

Add a get_preloaded_partition() function in AvbOps.  It provides an
alternative way to read a full parition (for checking its hash) without
performing a full memory copy. This also makes it possible to directly
boot the preloaded partition, rather than having to relocate the
loaded boot partition after avb_slot_verify().

TEST=Unit tests.
