This CL: Removes usage of the Windows.Media.Effects.AudioEffectsManager UWP API which was complex to use and only resulted in log messages that were not utilized for any essential task. Adds new methods if the EnforceSystemEchoCancellation flag is enabled. These methods use IAudioEffectsManager::GetAudioEffects to enumerate all available effects (instead of the old UWP API) and also checks that the system AEC really could be enabled for the selected input device. If not, a warning is logged. Adds basic support of SetOutputDeviceForAec which now assists an active AEC effect with the knowledge of that the default audio output device should be used as reference stream for the AEC. An example of a case where system AEC was enabled using a flag but the selected input device did not support it is shown in https://screenshot.googleplex.com/7ijVrnmRF8nWdpN Complete log: https://paste.googleplex.com/4790780437463040 And sample where the device does support the AEC effect is shown in https://screenshot.googleplex.com/98kb3NPSZC8VdkS Complete log: https://paste.googleplex.com/4915036173369344 Bug: 393098901 Change-Id: Ic3361fdd0ef2eba3e934b85b3f795dcd30a79612 Reviewed-on: https://chromium-review.googlesource.com/c/chromium/src/+/6233979 Commit-Queue: Henrik Andreasson <henrika@chromium.org> Reviewed-by: Olga Sharonova <olka@chromium.org> Cr-Commit-Position: refs/heads/main@{#1418560}

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
