Revert "Promote most UBSan flags to the ASan configuration on non-Windows"

This reverts commit 36c0df1671dccd3a8f76248d521c918e6c873afc.

Reason for revert: It seems the combination of UBSan, ASan, and fuzzer
instrumentation makes browser tests run far too slow. (Or there's some
deeper error being suppressed that I can't figure out, but it seems to
just be slow.) I suspect we'll need to make UBSan into a separate
bot.

Original change's description:
> Promote most UBSan flags to the ASan configuration on non-Windows
>
> This ratchets these in so we don't regress them. The alignment and null
> checks are not yet clear, so keep them on the FYI configuration for now.
> To avoid needing to introduce another set of builders, enable them on
> the ASan builders.
>
> This does not enable on Windows yet because the bots are not yet
> clear. First, -fsanitize=object-size will need to be suppressed due
> to https://github.com/llvm/llvm-project/issues/31914. Beyond that,
> there are some issues in
> https://ci.chromium.org/ui/p/chromium/builders/try/win-asan/11240/overview
> that I have not been able to diagnose yet.
