Subject : Revert "Send input event IPCs directly from the UI thread"
Author  : rockot
Commit description:
  
This reverts commit 868f89e764ab0e807adb237f0cbaf79ca5f49257.
See https://codereview.chromium.org/1991323002 for the original
CL.

Per offline discussions: there was no clear benefit from
using SendNow for input events, and having the extra interface
adds unnecessary complexity given that nobody is going to work
on porting Send call sites.
