Initial commit of updates required for core-v-verif to match state of cv32e40s rtl
Created by: silabs-hfegran
This commit pulls in 0.2.0 version of the ISS and updates simulation environment to match changes in rtl.
Note to reviewers: This will fail ci_check:
- hello_world: misa mismatch with iss, iss does not set bit 23(X) to 1.
- illegal_instr_test: test requires update, pending iss update to enable proper feature set
- Any of the interrupt tests: known error, being addressed in parallel effort.
