Emilio Cobos Álvarez c7d8e549f3 Bug 1848357 - Cleanup layer observer handling. r=mconley,gfx-reviewers,bradwerth
This seems to work, and turns out I need to fix this before bug 1847584,
because the epoch handling breaks with those patches in the case
customize mode sets display: none on browser elements.

Instead of dealing with epochs, just always report the last "has layers"
state to BrowserParent. This is both simpler and more reliable (there
were a couple hacks in WebRenderBridgeParent to make sure we notified
even though a transaction failed).

AsyncTabSwitcher pretty much already deals with this correctly because
it already needs to deal with browsers that already have layers, we only
had to loosen some assertions for potentially previous messages which
are fine.
