We maintain a simple LRU cache of tab layers by setting their
docShellIsActive = false with preserveLayers(true). Once they
are pushed out of the cache by more recently used tabs, their
layers are discarded.
Luckily most of the complexity of this could be contained in
the AsyncTabSwitcher - the one change that had to sit outside of
that was moving the aTab.closing = true earlier in the removeTab
call, so that we could use that information to eagerly evict tabs
from the cache. This was to address a leak in a few tests on try.

Sphinx has been complaining about a number of reStructuredText warnings
for a while. Fix all the ones in .rst files.
Not asking for review because this is docs only and changing .rst files
can't break anything important.
