Split OverviewToAllApps for Go

This CL swaps out the current OverviewToAllApps touch controller with
the Go specific implementation. Moreover, since we only use this class
in landscape, we rename it to LandscapeStatesTouchController to avoid
confusion.

Bug: 114136250
Test: Manual test NexusLauncher, Launcher3QuickstepGo, Go recents
