feat: add isCapableOfReceivingVideoCodec

[SomeBody16]

• Implemented isCapableOfReceivingVideoCodec method to determine the presence of H.264 and AV1 codecs, respectively.
• Added unit test to validate their functionality.

Will take a look at the code, but I'm not sure about putting this in web-capabilities. I think the original intent with web-capabilities was more browser API support type stuff, as opposed to media-level/SDP negotiation like this. Like, I don't think we'd put check for things like "mid-rid" or "simulcast" in here, and codec-level stuff to me feels like it's on the level of stuff like that, as opposed to things like "is some w3c api supported"

If WebCapabilities class is for w3c apis then maybe new class for CodecInfo that can tell us info about current browser codecs like BrowserInfo tells us about current browser
