Revert "Temporarily re-add content/renderer/input/OWNERS"

This reverts commit ff8d2bea.

Reason for revert: This change was temporary to unblock https://chromium-review.googlesource.com/c/chromium/src/+/2422181 which has now landed.


Original change's description:
> Temporarily re-add content/renderer/input/OWNERS
> 
> When content/renderer/input was moved[1] it removed the OWNERS file. However
> content/renderer/android/OWNERS lists it as a dependency.
> 
> This leads to any changes to content/renderer/android to fail presubmit, due to
> the missing file. This includes changes to remove that dependency in the OWNERS.
> 
> This change temporarily re-adds the file so that the dependency can be removed.
> 
> Removing the dependency will be done in a follow-up[2]. After which this change will be reverted.
