PSA: Removing id parameter in ADM factory method

[Henrik Andreasson]

I have recently landed 22480 which changes the signature of the ADM factory method by

removing an unused id parameter.

// NEW

static rtc::scoped_refptr<AudioDeviceModule> Create(const AudioLayer audio_layer);

// OLD (deprecated)

static rtc::scoped_refptr<AudioDeviceModule> Create(const int32_t id, const AudioLayer audio_layer);

The old signature is still present to give clients some time to phase out the old signature.

I plan to remove the old version within two weeks.
