Add a memory waterfall win/asan bot (and matching trybot), src/ side

While here, also slightly reorganize chromium.memory console layout:
- Consistently use OS as toplevel subcategory (so that we don't have
  the cros msan bots under "linux|cros" while the cros asan bots are under
  "asan|cros"
- Order OSs in the same order as the per-os waterfalls appear on
  build.chromium.org: win, mac, linux, cros.

In mb_config.pyl, remove obsolete 'x86' from win/asan config names,
and stop explicitly passing 'x64' (it's the default).

This adds the bot config, but it doesn't add any tests yet. I'll do this
in a follow-up so that I can send try jobs before adding tests. Before
tests are landed, the bot will do nothing.
