1261812 - Ensure Windows build/test machines have Windows Error Reporting configured to write local dumps, but suppress WER UI

Status: RESOLVED FIXED

Bruce Dawson (a Googler) tweeted a link to a change he made in Chromium's Windows builder setup:
https://codereview.chromium.org/1825163003/diff/60001/win_toolchain/get_toolchain_if_necessary.py

Setting those two registry keys ensures that Windows Error Reporting will write minidumps to a local folder (%LOCALAPPDATA%\CrashDumps), but not display the crash dialog (which tends to hang things in automation).

We should ensure that those two registry keys are set on our Windows build and test machines, so we're not getting unnecessary crash dialogs, but are getting minidumps that are useful for diagnosing unhandled crashes.

Sounds like grenade fixed this for Taskcluster workers, so that should be sufficient.
