ext4crypt: support wrappedkey for FBE

Qualcomm devices use a special `wrappedkey` mode for FBE. This is ported
from CAF
https://source.codeaurora.org/quic/la/platform/system/vold/commit/?h=LA.UM.7.8.r4-01000-SDM710.0&id=9229262d893a8592f7bc1b4e8a8dab7aad8df68c,
originally by folks at Mokee for vold
https://mokeedev.review/c/MoKee/android_system_vold/+/34102.

This patch ports the above changes to `ext4crypt`, which we can use in
recovery. Note that since we do not have `fs_mgr` in the recovery, we
cannot read the `wrappedkey` flag from fstab. Instead, similar to
`fbe.contents`, we use a special property `fbe.data.wrappedkey` to
indicate support for wrappedkey mode. Devices that need to use this
should set this property to `true` to activate corresponding code.
