Cv32e40x/merge dev to rel 57

Created by: silabs-robin

First steps of 2022's first merge procedure. Passes "rel_check" using xcelium.

Note: We disabled some known failures in "rel_check" to get this passing. (That might have been unnecessary and we might do it differently the next time.) The disabled tests will be re-enabled once the master branch is being propagated back onto the dev branches.
