ITS: Match largest preview size with video encoding capability
This test queries largest supported preview resolution, which is
used by test case to create video recording session. However,
max video encoder size on low-end targets may not match largest
preview resolution, so encoder creation may fail.
In short, video recording session should be created based on
platform's video capabilities.

Test: run scene4/test_preview_aspect_ratio_and_crop by Qualcomm
Flag: TEST_ONLY
