camera2: Fix parcelling of sensor pixel modes.

OutputConfiguration.writeToParcel previously used writeList to parcel
the List<Integer> mSensorPixelModesUsed. The Integer list read from a
Parcel into a vector of int32_ts in cameraserver native code, doesn't get read correctly
(values sent are not the ones received).
Therefore, instead we explicitly convert the Integer list into an int[]
before parcelling using writeIntArray. We also explicitly use
readInt32Vector on the native side in readFromParcel now.

Bug: 184396641

Test: atest RobustnessTest.java#testConfigureInvalidSensorPixelModes
