exo: Allow a shell surface to act as an overlay
Set up an overlay manager that allows an exo::ShellSurface to become an
overlay on top of a different window.
The initial use case is for a Android Play Billing popup to overlay a
Trusted Web App, when the app invokes a Payments API.
The shell surface must use the revised
aura_shell_surface::set_client_surface_str_id request to set a valid
overlay token.
The code to have the payment component hook into the overlay manager is
in a followup CL.
Bug: b:172592701
Test: Test Payment app shows the Play Store overlay
