Allowing R and S developer GSI for DSU

Adding new keys to allow a device boot a R-Deverloper-GSI and
S-Developer-GSI, respectively.

Also removing previous keys for R-Compliance-GSI and
S-Compliance-GSI, respectively. We will be allowing CTS-on-GSI
to run on unlocked state in R and later releases.
