Use livekit's Rust SDK instead of their swift SDK (#13343)

See https://github.com/livekit/rust-sdks/pull/355

Todo:

* [x] make `call` / `live_kit_client` crates use the livekit rust sdk
* [x] create a fake version of livekit rust API for integration tests
* [x] capture local audio
* [x] play remote audio
* [x] capture local video tracks
* [x] play remote video tracks
* [x] tests passing
* bugs
* [x] deafening does not work
(https://github.com/livekit/rust-sdks/issues/359)
* [x] mute and speaking status are not replicated properly:
(https://github.com/livekit/rust-sdks/issues/358)
* [x] **linux** - crash due to symbol conflict between WebRTC's
BoringSSL and libcurl's openssl
(https://github.com/livekit/rust-sdks/issues/89)
* [x] **linux** - libwebrtc-sys adds undesired dependencies on `libGL`
and `libXext`
* [x] **windows** - linker error, maybe related to the C++ stdlib
(https://github.com/livekit/rust-sdks/issues/364)
        ```
libwebrtc_sys-54978c6ad5066a35.rlib(video_frame.obj) : error LNK2038:
mismatch detected for 'RuntimeLibrary': value 'MT_StaticRelease' doesn't
match value 'MD_DynamicRelease' in
libtree_sitter_yaml-df6b0adf8f009e8f.rlib(2e40c9e35e9506f4-scanner.o)
        ```
    * [x] audio problems

Release Notes:

- Switch from Swift to Rust LiveKit SDK 🦀
