Add Android-backend to the memory_inspector (parsers).

Add the classes (and corresponding unittests) which implement
the Android-specific parst of the memory tracers.
The classes being introduced by these CL allow to:
 - Dump memory-maps using memdump.
 - Dump native allocations using Android's am dumpheap -n.
 - Grab OS and process stats using tools/ps_ext.
 - Deploy the prebuilt binaries to the device.

Store validation key in policy cache to enable key rotation

Track the validation key used to sign the policy signing keys
in the policy cache, so we can use the same key to verify the

Also clears the public key version in the policy, so the next
policy fetch will force a key rotation.
