Georges Basile Stavracas Neto 548073ec27 screen-cast-stream-src: Support DMA buffer sharing
Implement PipeWire's add_buffer and remove buffer, try and export
a DMA buffer first and, on failure, fallback to memfd.

When DMA buffers are successfully created and shared, blit the
framebuffer contents when drawing instead of downloading the pixels.
