1c6cf7c74a Merge logic of DICE HAL and diced in to dice-service 
The DICE HAL and diced are replaced with dice-service which implements
the diced services and also contains the HAL logic directly, without
exposing an implementation of the HAL service.

766caba5de Modify sepolicy for compos key changes 
Add the compos_key_helper domain for the process which has access to
the signing key, make sure it can't be crashdumped. Also extend that
protection to diced & its HAL.

Rename compos_verify_key to compos_verify, because it doesn't verify
keys any more.

Move exec types used by Microdroid to file.te in the host rather than
their own dedicated files.
