Build/Test Tools: Add input for skipping Playwright steps.

In older branches utilizing Puppeteer instead of Playwright, installing Playwright browsers is unnecessary and resulting in workflow failures.

This introduces a new `install-playwright` input that allows older branches to indicate that Playwright related steps should be skipped.

See #63117.
