Add string name for V4L2_CTRL_FLAG_HAS_WHICH_MIN_MAX.

Test that V4L2_CTRL_WHICH_MIN/MAX_VAL behaves as expected.
1. Calling G_EXT_CTRLS successes when V4L2_CTRL_FLAG_HAS_WHICH_MIN_MAX is set
   and returns -ENVALID if the flag is not set.
2. S_EXT_CTRLS and TRY_EXT_CTRLS always return fail.

Tested with VIVID:
