Video Capture: update capturing dimension based on camera orientation

With device's native orientation being Portrait mode, for devices with
camera orientation of 0 or 180 degs, the capturing width and height
needs to be swapped in order to capture in respect to device's current
orientation.

Bug: 1032902
Test: Duo calling on devices with different camera orientation
