Update components and docker images
These changes are motivated by wanting to support building and running the rmm-v1.0-eac5 CCA release.
As a consequence, TFA has been updated to 2.10, and improvements have been made to take advantage of its new feature auto detection capability.
The docker images have also been updated for newer FVP and toolchain releases.
Finally, I've added automated boot testing for ffa-tftf.yaml.
