Revert of CQ: enable win_chromium_compile_dbg_ng

Revert of CQ: enable win_chromium_compile_dbg_ng (patchset #1 id:1 of https://codereview.chromium.org/853933003/)

Reason for revert:
There are pending jobs (10 right now).

I just noticed that win_chromium_compile_dbg_ng uses a small number of win VMs as its pool, while win_chromium_compile_dbg uses the standard windows one.
