lavfi/vf_hwupload: Add support for HW -> HW transfers
As we find ourselves wanting a way to transfer frames between
HW devices (or more realistically, between APIs on the same device),
it's desirable to have a way to describe the relationship. While
we could imagine introducing a `hwtransfer` filter, there is
almost no difference from `hwupload`. The main new feature we need
is a way to specify the target device. Having a single device
for the filter chain is obviously insufficient if we're dealing
with two devices.
So let's add a way to specify the upload target device, and if none
is specified, continue with the existing behaviour.
We must also correctly preserve the sw_format on such a transfer.
