This removes from the output of `./mach test-unit` hundreds of lines

This should help identify flaky unit tests, since codecov will gather
statistics of tests (of the last 60 days) and allow us to easily
identify flaky unit-tests. [Test page on
codecov](https://app.codecov.io/github/servo/servo/tests) based on an
uploaded report from a try run.
Additionally add a catch-all parameter for `test-unit` which is passed
through to the `cargo nextest` invocation, useful for e.g. stressing a
test via `--stress-count`.
Testing: Manually tested with [try
run](https://github.com/servo/servo/actions/runs/18529823800)

Follow-up to #39812, using nextests builtin retry feature to rerun flaky
unit-tests.
This also adds a per-test timeout, replacing the global timeout set for
the retry action. We could also add a global timeout for nextest tests,
but per-test timeouts should be sufficient and noticably speedup CI when
individual unit tests get stuck.
Testing: [mach
try](https://github.com/servo/servo/actions/runs/18519094535) running
the unit-tests with retries in CI.
