[RSDK-9458] Remove 'Stream' from Camera interface

[randhid]

The merge conflicts on Sean's PR will likely be terrible when he gets back in 2.5 weeks, so I'm using this branch to keep it recent.

I also think we're at a point where we can merge. I'm adding the original testing Sean did to the end of this comment.

Requests: @bhaney, could I have a config to test one of the vision services with to ensure DecodeImageFromCamera does not break them?

Original PR + comment

Tests

✅ Test webcam Darwin
✅ Test webcam switch inputs Darwin
✅ Test RTSP with passthrough and without

Re-testing after long time (my, Sean, vacation)

• Test transform crop and rotate
• Test ffmpeg with mediamtx
• Test fake
• Test image_file
• Bijan's config for vision (person detection and other tf model)

There's a lot of files changed here. Am I correct that these changes to VideoSource/Camera/StreamCamera are the only real changes and everything else is the refactor to appease the compiler?

[randhid]

Kind of - in the process of deprecating Stream, different methods are being used in vision, and the stream server now takes context to refresh the streams - I can break up this pr into independent pieces and remove some of sean yu's renames to make it smaller, I do think this was the diff that made the most sense for his manual testing.

[randhid]

The camera driver changes + the new StreamCamera interface (ffmpeg, transformpipeline, webcam) are there to appease the compiler without refactoring those drivers intensely.

@bhaney I like Rand's idea of testing with a vision config. Could/did you send that over?

He sent me a service but @bhaney it's not working with vanilla viam-server, could you send another one over?
