Use BrowserCommandController's logic uniformly for bookmark command enable/disable

Use BrowserCommandController's logic uniformly for bookmark command enable/disable

The logic for updating the bookmark command enable/disable state does
not take the appropriate state into account on extension load/unload,
resulting in e.g. bookmarking potentially not being disabled in popup
windows. Just reuse the BrowserCommandController's logic instead.

TEST=verified Ctrl-D in popup after extension enable has no effect
