Separate "Build, Test, Lint for Pull Requests" workflow

[uarlouski]

The testing workflow should be separated into two workflows with the following checks:

• workflow with cheap checks that runs on every push without any approvals, it includes ESLint, Jest tests
• workflow with long running checks that runs on ready-to-test label, it includes all playwright tests (on only new one so we will pw tests in parallel reducing the pipeline duration by ~8 min)

addtionally need to ensure that only one visual tests suite running in time because we have limited number of available threads in applitools, there are limitations of concurrency property and request to improve it https://github.com/orgs/community/discussions/12835
