Revert "Add one-stop-shop for built-in AEC toggling in APM"

Browse Source 
This reverts commit 771b50ca0b92477ce8aabba025e959790dd1a949.

Reason for revert: Introduces error-prone config.

Original change's description:
> Add one-stop-shop for built-in AEC toggling in APM
> 
> This does not change what AEC functionality is available.
> However, a client that only uses this interface - and not the submodule
> pointer accessors - gets simpler code, and is guaranteed not to run any
> two AECs in tandem.
> 
> The submodule interface EchoControlMobile is being deprecated in
> https://webrtc-review.googlesource.com/c/src/+/89392
