Was reverted a while ago, brave/brave-core@d201ff6 brave/brave-core#4371 I honestly forgot about this.

If we need to re-hide the mic, it'll be easier to just use a cosmetic.

Yeah, if the hide is in brave-specific list it shouldn't break any tests like what happened in brave/brave-core#4371.
cc @iefremov and @bsclifton, this would (re-)add a cosmetic filtering fix while we're figuring out #3725

@Brave-Matt Is this working better? does it work well on all the platforms?

[ryanbr]

Checked IOS, Android and Desktop now fixed.

We can revisit this later, basically Android google voice search is fine, no need to hide it. IOS and Desktop doesn't work.
Android and desktop share the same filters, so no way seperate the rules currently, lets revert this for the sake of compatibility on Android.
