alloy: Enable BackForwardCache support (see issue #2421)

Browse Source 
BackForwardCache is currently being tested via field trials (see
https://crbug.com/1171298) and can be explicitly disabled using the
`--disable-back-forward-cache` or `--disable-features=BackForwardCache`
command-line flags. The default behavior now matches the Chrome runtime.
