Revert of Moving mac_chromium_asan_rel_ng to cq_builders for better resource allocation

Revert of Moving mac_chromium_asan_rel_ng to cq_builders for better resource allocation (patchset #1 id:1 of https://codereview.chromium.org/1597553003/ )

Reason for revert:
We're now seeing pending queues for CQ builders in this pool.

mac_chromium_asan_rel_ng is not a CQ builder, so moving it back to optional pool. I'm also removing it from a CQ experiment, see https://codereview.chromium.org/1611163002 .

If you'd like to request more resources, please do so explicitly.

> Moving mac_chromium_asan_rel_ng from optional1_builders to cq_builders for better resource allocation
> Since optional1_slaves only has 2 bots, it is possible for the estimated resource capacity to reach 6 based on the past month's load. cq_builders has capacity of around 90 bots and seldom goes above 60, so requests to mac_chromium_asan_rel_ng can be handled by bots in cq_builders instead to prevent jobs from piling up in the pending queue.

FWIW, I don't think this revert was necessary, since the builder was removed
from CQ experiment. And I also don't think we need to allocate more machines for
a 10% experiment - we already have enough. 

I suspect a bug in "git cl try" which triggers experimental builders by default,
and that's the cause of the problem.
