[Profiler] Android File Transfer app interferes with adb which causes Profiling device to disconnect



Before testing make sure you have Android File Transfer app

How to reproduce:
1. Create a new project
2. Open Profiler window
3. Open build setting and keep autoconnect off, enable development
4. Build and run empty scene on 2 Android devices
5. Find and select on of the devices in Profiler dropdown (devices should be connected via USB)
6. Press Record Profiling information
7. Disconnect device which is not selected in profiler from USB (another one is still being profiled)
8. Reconnect that device with USB

Actual result: Android File Transfer app starts on Mac, it interferes with adb and device you were profiling disconnects in Profiler

Reproducible: 2021.2.0a13.1875

Tested and reproduced with these devices:
VLNQA00152, HUAWEI P9, 7.0.0, HiSilicon Kirin 955, Mali-T880
VLNQA00323, Galaxy Note10 USA, 10.0.0, Snapdragon 855 SM8150, Adreno 640

    Resolution Note (2021.1.X):

    Android's file transfer app on OSX will hijack adb completely and mess it up for us, should be added as a known issue. We don't really have a way to stop that apart from the user clicking fast on the confirmation button in file transfer in order for their device to still show up in the drop down (there is always a 5 second scan window for usb)
