[chip, dv] Move OTP image generation to DVSim

There are a few updates in this commit.
1. The initial OTP image generation was handled by meson build.
Unfortulately, that prevents us from modifying the OTP image generation
in the extended closed source env which has a different OTP memory
layout than our generic model. The OTP generation step for DV is done
via DVSim (added to chip_sim_cfg.hjson as a `pre_run_cmd`)
2. All available OTP image flavors (for LC state RAW, DEV and RMA) are
constructed by default.
3. The chip_env_cfg now has supprt for choosing which of these flavors
to pick via a plusarg.
