test: introduce #smoke tests (#11135)
This patch introduces 109 "#smoke" tests - a subset of tests that makes
sure that basic Playwright functionality works. This set is loosely
defined; feel free to add/remove tests to the set. The only goal is to
keep this set minimal & fast to run.

I tried to pick tests so that various parts of Playwright functionality
are exercised.
