[ci,acc] Adds support for ACC PQC smoke test in Verilator and adds it to CI

[apinise]

This PR restructures the previous configuration for passing the PQC parameter from a simulation config to the DV environment.

• Removes the use of environment variable and instead adds a -CFLAG to configure the iss_wrapper.cc at build time which will create the accsim ISS model.
• Verilator pre_dv fusesoc core now accepts a --flag pqc to configure the ACC instantiation and appropriate core dependencies/-CFLAG options.

It also updates the smoke_pqc directory to use the appropriate fusesoc invocation and integrates into CI

• Updated the Verilator waiver to prevent warnings with KMAC after instantiating into the testbench. Warnings consisted of UNUSED for signals in the top-level testbench used for visibility, UNOPTFLAT for combinational assignments to struct fields that rely on the value of other fields in the same struct, and VARHIDDEN for having multiple FSM in KMAC that share state names in their enum declarations.
• Updated the expected smoke_pqc/smoke_test.s results based on model behavior after adding a KMAC transaction and the vector instructions.
• Added a new CI test to run the ACC PQC smoke test on verilator with the vector ISA hardware.

The existing ci.yml file had a typo in OTBN having been named OBTN and the name was updated to ACC. The same typo existed in the sw/device/tests/penetrationtests/firmware/fi/acc/*.s assembly files and has been updated as well.
