libgui: ConsumerBase-based classes now create their own BufferQueues

Using ConsumerBase-based classes is now the recommended way to create
BufferQueues.

This also includes a few new methods that are used by downstream classes
to avoid calling methods on raw IGBP/IGBCs.

I decided to keep and deprecate the old ctors temporarily. Before I roll
the flag out I'll remove them, but this way I can build the whole build
with or without the flag.

This is an important step for go/warren-buffers, because it consolidates
usages of BufferQueues to supported APIs and reduces the libgui API
surface that exposes IGBP/IGBC.

BYPASS_IGBP_IGBC_API_REASON: this CL is part of the migration.
