Integrate the new file encryption framework

These changes integrate new file encryption framework to use new V2 encryption policies.

These changes were earlier reverted in 'commit 4211691d ("Reverting crypto and incrementalfs changes")',
as part of android-4.14.171 merge from Android common kernel. This patch attempts to bring them back
post validation.
