Reason for revert:
We got a new error on this again, so I'm removing this trybot from the CQ again: https://build.chromium.org/p/tryserver.webrtc/builders/win_x64_clang_dbg/builds/2335/steps/compile/logs/stdio
Original issue's description:
> Revert of CQ: Disable win_x64_clang_dbg trybot (patchset #1 id:1 of https://codereview.webrtc.org/1850113002/ )
>
> Reason for revert:
> I think the bug has been making enough progress for us to turn this back on (Chrome turned on their trybot).
> I fired of builds and now have 6 green ones in a row.
