FsCrypt update: support fscrypt policies v1 and v2

This patchset introduces support decryption for Android 11.

In this update we deprecate ext4crypt. To specify the
policy version to use, use TW_USE_FSCRYPT_POLICY := 1 or
TW_USE_FSCRYPT_POLICY := 2. By default policy version will
be set to 2 if this variable is omitted.
