android: camera_device: Postpone mapped streams handling

Mapped streams are generated by post-processing and always require a
source buffer to process image data from.

In case a Mapped stream is requested but its source stream is not, it
is required to allocate a buffer on the fly and add it to the
libcamera::Request.

Make sure a source stream is available for all mapped streams, and if
that's not the case, add a dedicated buffer to the request for that
purpose.
