* fix: duplicate simulcast entries

* remove duplicate declaration

* remove duplicate audioDeviceModule

* fix: removed livekit's external audio processor

* fix: add back simulcast factories

* Fix missing RTC_OBJC_TYPE macros

* Fix missing headers and Metal linking

# Conflicts:

* Fix Mac Catalyst `RTCCameraVideoCapturer` rotation (#126)

* Fix set frame transformer (#125)

* Fix webrtc_voice_engine not notifying mute change (#128)

Looks like this line was missed during the m125 update.

webrtc-sdk/webrtc@272127d#diff-56f5e0c459b287281ef3b0431d3f4129e8e4be4c6955d845bcb22210f08b7ba5R2289

Adding it back in so that mic is properly released when muted.
# Conflicts:
#	media/engine/webrtc_voice_engine.cc

* android: Allow for skipping checking the audio playstate if needed (#129)

Pausing/stopping the audio track can lead to a race condition against
the AudioTrackThread due to this assert. Normally this is fine since
directly pausing/stopping isn't possible, but user is using reflection
to workaround another audio issue (muted participants still have a
sending audio stream which keeps the audio alive, affecting global sound
if in the background).

Not a full fix, as would like to manually control the audio track
directly (needs a bigger fix to handle proper synchronization before
allowing public access), but this will work through reflection (user
takes responsibility for usage).

* Allow to pass in capture session to RTCCameraVideoCapturer (#132)

Expose initializers to pass in capture session to RTCCameraVideoCapturer
so we can use AVCaptureMultiCamSession etc to capture front and back
simultaneously for iOS.

* Fix NetworkMonitor race condition when dispatching native observers (#135)

There is a race condition in NetworkMonitor where native observers may
be removed concurrently with a notification being dispatched, leading to
a dangling pointer dereference (trying to dispatch an observer that was
already removed and destroyed), and from there a crash with access
violation.

By ensuring dispatching to native observers is done within the
synchronization lock that guards additions/removals of native observers
protects against this race condition. Since native observers callbacks
are posted to the networking thread in the C++ side anyway, there should
be no risk of deadlock/starvation due to long-running observers.

* Add isDisposed to MediaStreamTrack (#140)

* chore: handle invalid cipher from key size. (#142)

* Allow software AEC for Simulator (#143)

~Allow to use "googEchoCancellation" constraint for software AEC.
For devices "googEchoCancellation" should be false to use
VoiceProcessingIO.~

* fix: Fix bug for bypass voice processing. (#147)

* chore: remove aes cbc for framecryptor. (#145)

* Change audio renderer output format (#149)

Instead of converting to Float, output original Int data without
conversion.
Output the raw format and convert when required.

* Fixed issue with missing network interfaces on iOS (#151)

Related issue: webrtc-sdk/webrtc#148
Cherry-pick :
https://webrtc.googlesource.com/src/+/fea60ef8e72fb17b4f8a5363aff7e63ab8027b4f

Fixed issue with network interfaces due to a missing return value in the
"nw_path_enumerate_interfaces(...)" block. Exposed in iOS 18,
RTCNetworkMonitor::initWithObserver will only enumerate the first
interface, instead of all device interfaces
