[gwen2018]

This is part b fix to additional issues found when switching between 2d and 3d.

Changes:

1. release frame resources when switching between 2d and 3d
2. handle cases when only depth, no rgb, is part of the stream
3. handle cases when no depth is part of the stream

Tracked on: DSO-16584

Please confirm that the memory profiler has been used in order to check that no leak happens because of these changes.

[gwen2018]

@remibettan yes, checked with both memory profiler and process profiler, memory did not leak over time after 200 2d-3d switches. The only time memory increases persistently is the first switch to 3d which we does setup for 3d display. in subsequent 2d-3d switches, memory all recovers - native memory recovers once switch back to 2d. java memory gradually recovers as part of garbage collection.
