Place auto translate feature behind a flag that where rollout of the feature can be controlled via griffin.

The above requires 1.46.138 or higher for 1.46.x verification 👍 I think one platform for both Desktop & Android is enough. Maybe run through macOS as I went through Win 11 x64 on Nightly as per https://github.com/brave/brave-variations/pull/479#issuecomment-1340356174. As per @rebron, we won't be pushing the Griffin study on the Release channel until we have more information from the Nightly & Beta channels.

@brave/qa-team can follow the STR/Cases outlined via https://github.com/brave/brave-variations/pull/479#issuecomment-1340356174 & https://github.com/brave/brave-variations/pull/479#issuecomment-1340400758 but use the flag mentioned via https://github.com/brave/brave-core/pull/16185#issue-1471452908 rather than using Griffin staging like I did.

Probably should exclude this from the notes as this will be enabled a bit after the release. @LaurenWags @rebron please re-add if you feel differently.
