bigbiff 7ba7500953 decrypt: AOSP 10 requires the use of fscrypt
fscrypt aosp doc: https://source.android.com/security/encryption/file-based
kernel fscrypt doc: https://www.kernel.org/doc/html/v4.18/filesystems/fscrypt.html

This commit implements the ability for TWRP to use fscrypt to decrypt
files on the fscrypt implementation. It has been implemented mostly
in a new successor library to e4crypt called libtwrpfscrypt. Most of the
code was ported from AOSP vold.

Notable updates include:
 - updated policy storage by libtar
 - lookup of fbe policies by libtwrpfscrypt
 - threaded keystore operations

Big thanks to Dees_Troy for the initial trailblazing
of encryption in TWRP.
