Camera2: fix FC when switching camera in video mode

mFocusManager's manager needs to be updated before startPreview,
otherwise setParameters will be called with an invalid preview
mode resulting in a crash on some device (in this case, aries).

Add an option to maintain the focus mode when using touch-to-focus

There's at least one family of camera HALs that gets "confused" when
the focus mode forcefully changes to auto after setting focus /
exposure area options.

Sticking with the current focus mode still results in effective use
of the focus region, so don't force a switch to auto. The default
behavior remains the original, this needs to be explicitly enabled
on affected devices
