Add logic to adapt snackbar timeout based on actions

[richtabor]

Currently snackbars have a hard-set 10000 timeout. While this is appropriate perhaps for some notices (those that have actions), snackbars without actions should be much quicker.

For example, a notices that fires after you run a command (like "Hide block breadcrumbs" or when you copy a block to your clipboard "Copied "button" to clipboard" are informative, not action-seeking. You shouldn't have to interact with them (other to dismiss if they're hanging around and stacking up.

One idea is to have the NOTICE_TIMEOUT adapt based on if the notice has an action. If it does, then perhaps a longer value like 10000 is fine; otherwise something much smaller (even 5000) may work much better. We'd need to test around the specifics, but it could be much shorter.

const NOTICE_TIMEOUT = 10000;
