This patch shuffles around most of the detachable UI code to try to make
it more readable and maintainable. The goal is to get the business logic
out of the main UI loop functions as much as possible, and concentrate
the code handling each individual menu option in a single location.
This is a pure refactor and should not change behavior in any
(important) way. The adjustments to unit tests are only needed since the
old code displayed the same screen twice in certain circumstances, and
returning from the LANGUAGE menu to DEVELOPER selected the default
option Power Off, although other transitions to that screen select the
current default boot target.

The region API was a way for firmware and kernel verification to get
at various blocks of caller-provided data. In practice, we only used
it internally as a way to get at parts of the GBB. Prune it down to
access only the bits of GBB we still need, from the buffer we already
know we have.
In the long run we should use the same vb2ex_read_resource() API that
vb2 firmware verification does, but that should be done in a follow-up

Vboot firmware previously supported a rather complex audio looping
library. Our original intent was to allow developers to flash a
custom beep sequence / tune as an easter egg. We never fully
supported that, but the code to allow it lived on. Get rid of that.
Vboot also previously made no assumptions about the frequency of
VbExGetTimer(), which was only used by the vboot_audio library. So it
spent 10ms every boot measuring the frequency. Which is silly now,
because depthcharge implements that as a microsecond timer. Get rid
of that measurement and define the timer as a microsecond timer.
