Replace the `enable-experimental-ui-automation` switch with a disabled-by-default `UiaProvider` feature. Users must now start the browser with `--enable-features=UiaProvider` rather than `--enable-experimental-ui-automation` if they wish to manually enable the provider. As a consequence, tests that added the old switch to the process command line to enable the provider now use a ScopedFeatureList.
