Hans de Goede ea4baaacc3 libcamera: DmaBufAllocator: Support allocating from /dev/udmabuf ...

The dma-buf allocator currently allocates from CMA and system heaps.

Extend the dma-buf allocator to support allocating dma-buffers by creating
memfd-s and turning those into dma-buffers using /dev/udmabuf.

The buffers allocated through memfd/udmabuf are not suitable for zero-copy
buffer sharing with other devices.
