variations: add weblayer to testing variations

This adds 'android_weblayer' to nearly all places that 'android_webview'
is. The only places I did not add weblayer that have webview are for
autofill and ones clearly webview specific (such as WebViewWakeMetricsService).

BUG=1049426
TEST=test only change
