Add more build configurations for Coverity MISRA checks

This patch adds more configs for Coverity MISRA checks.
It covers more source files that are not covered right now.

Unlike the MISRA checks we have now, these are nominated,
i.e. they are only run on patches that touch specific source files.
Therefore, this patch also updates the nomination rules file.
I chose to create a new "tf-l2-coverity-misra-nominated" group to
differentiate them from the ones that are always run.

An ultimate goal is to move the configs (at least some of them) in the
"tf-l2-coverity-misra" group to the new nominated group as we don't
need to run all of them on every patch.
