Make renode_wrapper more configurable

[MateuszKarlic]

Allow to pass more options to renode_wrapper such as:

• CPU model
• privilege levels
• additional CPU constructor parameters

Also this adds an additional print to instr_trace_compare.py and allows to pass additional arguments to ISS with --iss_opts= switch.

This PR depends on: https://github.com/chipsalliance/riscv-dv/pull/984 and should be considered for merge only after those changes are applied. The first commit here is taken directly from that PR.
