avfilter/vf_libplacebo: support all supported pixfmts

Browse Source 
This is done only to the inputs, not the outputs, because we always
output vulkan hwframes.

Doing so also requires keeping track of backing textures for non-hwdec
formats, but is otherwise a mostly straightforward change to the format
query function. Special care needs to be taken to avoid crashing on
older libplacebo due to AV_PIX_FMT_RGBF32LE et al.
