The 'target-bitrate' property can be changed while PLAYING
(GST_PARAM_MUTABLE_PLAYING). Make it thread-safe to prevent concurrent
accesses between the application and streaming thread.

The Zynq UltraScale+ encoder implements a custom OMX extension to
directly import dmabuf saving the need of mapping input buffers.
This can be use with either 'v4l2src io-mode=dmabuf' or an OMX video
decoder upstream.

If the OMX component supports dynamic buffer mode and the input buffers
are properly aligned avoid copying each input frame between OMX and
GStreamer.
Tested on zynqultrascaleplus and rpi (without dynamic buffers).

No semantic change, just factor out the code enabling and disabling the
component to their own functions.
Makes the code easier to read as the set_format() method was already
pretty big. Will also allow us to easily change the enabling logic.
