Camera1: Handle multiple logical cameras with same facing

For Camera1-HAL3 shim, the camera ID filtering logic is revised to
handle case of multiple logical cameras facing the same direction,
and are backed by same/different set of physical camera IDs.

Example 1 (all facing back):
ID1 = ID3 + ID4
ID2 = ID5 + ID6

Example 2 (all facing back):
ID5 = ID1 + ID2
ID6 = ID3 + ID4

In both examples, only ID1 will be advertised to camera1 app.

Test: Check cameras on devices with multiple logical cameras
Test: Camera CTS
