[camera] Removed the microphone permission request from availableCameras on Web (#4263)

Browse Source 
I've removed the microphone permission request from availableCameras on Web. 
Adding an additional parameter would break either web or android/ios, so in my opinion it is better to change the web behavior.

Changes were made based on this issue: https://github.com/flutter/flutter/issues/112277
