* Update our cancel icon
The cancel icon we're using in the app has drifted out of sync with the ones used in our designs. We also had two identical-looking icons, so this consolidates them into one.
I've simultaneously updated our chevron icons, since in the case of the 'jump to unread' timeline button, it became clear that the weight of the new close icon did not match the thinner chevron.

This is to match the sticker picker setting we already have, but not exposed in the user settings until we decide if we actually want it to be there.
This is primarily intended to be used in environments that disable it at the config level, though given there's multiple people in the wild who have asked for this, it seems reasonable to expose it as a hidden setting instead. Note that as of writing it's not clear if any of those requests made it as far as an issue tracker.
Typically for the usecase presented we'd add a new UIFeature flag, however this *feels* wrong for the case at hand.
