Tests failing when running regression using Questa

Nobody has claimed this yet.

## Issue Description
Hi!

I'm trying to achieve regression results close to the ones described in the [nightly report](https://ibex.reports.lowrisc.org/opentitan/latest/report.html) locally. Several tests are showing a 0% pass rate. I've listed them below along with the associated error messages.

Can you please share any ideas on what might be wrong and how I can fix these issues?
The tests were run using the `make --keep-going IBEX_CONFIG=opentitan SIMULATOR=questa ISS=spike WAVES=0 COV=0` command. I am also attaching the log file. Please let me know if you need any additional information.

Thank you in advance for any guidance you can provide.

## My Environment

**EDA tool and version:** Siemens Questa Sim-64 2024.1_2

**Operating system:** Ubuntu 22.04.4 LTS

**Version of the Ibex source code:** 3937e484da24a09ae97820b2defe9a85fd7cea4e
I also had to make several adjustments, including some mentioned in this [issue](https://github.com/lowRISC/ibex/issues/2108), to be able to run everything with Questa. Here is the list of all modified files:
- dv/uvm/core_ibex/fcov/core_ibex_fcov_if.sv
- dv/uvm/core_ibex/fcov/core_ibex_pmp_fcov_if.sv
- dv/uvm/core_ibex/riscv_dv_extension/ibex_log_to_trace_csv.py
- dv/uvm/core_ibex/riscv_dv_extension/riscv_core_setting.tpl.sv
- dv/uvm/core_ibex/scripts/run_instr_gen.py
- dv/uvm/core_ibex/yaml/rtl_simulation.yaml
- rtl/ibex_tracer.sv
- vendor/google_riscv-dv/yaml/simulator.yaml

Start by reproducing the listed regression command with the reported Ibex revision and Questa version, then inspect the failures in dv/uvm/core_ibex/common/ibex_cosim_agent/ibex_cosim_scoreboard.sv and dv/uvm/core_ibex/tests/core_ibex_test_lib.sv. Compare the listed local modifications with the source revision and issue 2108. Done means identifying the cause of each failing test and documenting or implementing a reproducible fix.
