Limit preview stabilization mandatory stream sizes to 1440p (instead of RECORD).

Also fix a logic error in an if check while retrieving mandatory streams
for preview stabilization. This was not caught by CTS since for devices
where preview stabilization was supported, skipped the test. A
modification has been made to CTS RobustnessTest to ensure that the
preview stabilization support and mandatory streams are in agreement
with each other.

Bug: 228245412

Test: atest RobustnessTest.java on device supporting preview stabilization
