If a decice provides a StrongBox KeyMint instance then the default IRPC instance is required to use a proper, non-degenerate DICE chain. Expose a function to check whether the CSR contains a proper DICE chain and use that from VTS to implement the test.

KeyMint HAL
This directory contains the HAL definition for KeyMint. KeyMint provides cryptographic services in a hardware-isolated environment.
Note that the IRemotelyProvisionedComponent HAL, and it's associated types,
used to also be defined in this directory. As of Android U, this HAL has been
moved to a different directory (../rkp). This move is ABI compatible, as the
interfaces have been maintained. The build is split so that the generated
code may be built with different options.
