media: v4l2-ioctl: replace IOCTL_INFO_STD with stub functions

This change removes IOCTL_INFO_STD and adds stub functions where
needed using the DEFINE_V4L_STUB_FUNC macro. This fixes indirect call
mismatches with Control-Flow Integrity, caused by calling standard
ioctls using a function pointer that doesn't match the function type.
