This reverts commit aa20f9b8.

Reason for revert: Mac builders on perf waterfall are failing after this CL:
https://ci.chromium.org/p/chrome/builders/ci/mac-builder-perf

Original change's description:
> Cache Mac channel information
>
> Soon, with TargetChannel, an instance of Chrome on the disk
> might be upgraded to an instance of Chrome of a different
> channel. Cache the channel information on startup, so that
> even if it's changed, the channel information of the current
> running instance is available.
>
> Fixed: 1163159
