add video players

[zodiepupper]

we need to add video players that supports most popular file types.

i think we can get this pretty easy now because there's an addon for it now:
https://github.com/xiSage/godot-vlc

but it looks like it only has builds for windows rn, but seems like it shouldn't be too difficult to compile.
just need to find time to do it.

i think we can start off with the built in video player for now (meaning we only have ogv support for a lil bit). it won't be spatialized for a while until someone can create either a hook for the 3dpanels to intercept viewport audio listener stuffs or an object that uses the godot-vlc stuff but forces it to be 3d native and spatializes the audio.

i've already started work on the ogv import one. it's basically finished by now, just needs some script changes to add it to the main script that handles import and then also added to the asset import flow inside journaling.gd

we are using ffmpeg. i am working on an ffmpeg gdextension that will give us a texture that also provides the audio or whatever other data is needed from that ffmpeg decoder context.
