Cherry-pick 'Add Win Clang x86 builds.' to skqp/dev.

The tryjob Build-Win-Clang-x86-Debug is on the CQ, but the CLs to add
that tryjob and make it succeed have not yet been cherry-picked to
skqp/dev, so all CQ dry runs are failing. This CL cherry-picks the
necessary changes to skqp/dev. Also re-gen tasks.json.

Original description below.


Add Win Clang x86 builds.

Enable /arch:SSE2 for Win x86 builds (both MSVC and Clang).
