chore: use a single Progress instance for expect

[dgozman]

In the new strict progress mode, we can skip progress.race() calls and thus avoid being interrupted by the progress.

To support legacy mode, guarded by env.PLAYWRIGHT_LEGACY_TIMEOUTS, two new methods progress.pause() and progress.resume() are implemented. This will go away as soon as legacy mode is removed.

Closes #36236. References #35987.
