test: pytest: Add --quiet-hooks option

Add a --quiet-hooks option to suppress display of hook commands to
stdout while still logging them to the HTML log file. This reduces
console noise during test runs.

Cover-letter:
test: pytest and hook improvements
This series includes several improvements to the pytest infrastructure
and test hook configurations:

- Fix the timing check in conftest to properly check if timing is enabled
- Add a --quiet-hooks option to suppress hook command display
- Add and update ellesmere hook config files for various QEMU boards
- Update qemu-riscv64 config for S-mode with OpenSBI
