libcamera: debayer_cpu: Sync DMABUFs
Using `DMA_BUF_IOCTL_SYNC` is required for DMABUFs in order to ensure
correct output. Not doing so currently results in occasional tearing
and/or backlashes in GL/VK clients that use the buffers directly for
rendering.
An alternative approach to have the sync code in `MappedFrameBuffer` was
considered but rejected for now, in order to allow clients more
flexibility.
While the new helper is added to an annoymous namespace, add
timeDiff to the same namespace and remove the static definition as a
drive by.
