Pavel Labath b63c1c47b7 [lldb] Disable some unwind plans for discontinuous functions (#140927) ...

Basically, disable everything except the eh_frame unwind plan, as that's
the only one which supports this right now. The other plans are working
with now trying the interpret everything in between the function parts
as a part of the function, which is more likely to produce wrong results
than correct ones.

I changed the interface for object file plans, to give the
implementations a chance to implement this correctly, but I haven't
actually converted PECallFrameInfo (its only implementation) to handle
that. (from the looks of things, it should be relatively easy to do, if
it becomes necessary)

I'm also deleting UnwindPlan::GetFirstNonPrologueInsn, as it's not used,
and it doesn't work for discontinuous functions.
