v4l2 common: Fix build error when enabling verbose log of V4L2Device.cpp

SEQUENCE_CHECKER() macro does nothing when libchrome DCHECK flag is
not enabled. We cannot use ALOG_ASSERT() for the checker variable.
Also, we switched to Android ui::Rect class, which doesn't have
Contains() method. This CL fixes these issues.

Bug: 155138142
Test: mmm external/v4l2_codec2 with uncomment #define LOG_NDEBUG 0
