Brave Yao ef77ef3573 Revert "Desktop capturer: Add OnDisplayChanged callback"
This reverts commit d1208c26b1cdb536fdec942207033711101d5d26.

Reason for revert: This cl causes the crashing issue as in
chromium:916961 at starting desktop capture on Windows.

Original change's description:
> Desktop capturer: Add OnDisplayChanged callback
>
> This adds support for a new DesktopCapturer::Callback method
> OnDisplayChanged that is sent at the start of a desktop capture
> session and whenever the display geometry changes.
>
> This cl adds the basic structure to call this api at the start
> of the capture session. Currently Windows only.
>
> A follow-up cl will add support to call this whenever the display
> geometry changes.
>
