Julius Werner 3f896a5b63 Add new GBB_FLAG_FORCE_MANUAL_RECOVERY ...

It seems like there are some testing use cases where we want the device
to boot into the recovery installer but it is impractical to fully
simulate a user-triggered recovery. This has become impossible with the
recent change to always require manual recovery to boot an image, even
when the developer mode switch is enabled (CL:924458).

This patch adds a new GBB flag to support this use case. When the flag
is set, all recovery mode is manual recovery mode, regardless of wheter
the developer mode switch is on or not.

Since the GBB_FLAG_ENABLE_SERIAL was killed off before it ever really
worked anyway, we can safely reuse the bit reserved for it.

BRANCH=None
BUG=None
TEST=make runtests, manually confirmed on Kevin
