SurfaceControl: Add setDropInputMode api
Introduces an API to drop input events on this SurfaceControl. This
policy will be inherited by its children. The caller must hold the
ACCESS_SURFACE_FLINGER permission.
Options include:
ALL: SurfaceControl and its children will not receive any
input regardless of whether it has a valid input channel.
These policies are used to enable features that allow for a less trusted
interaction model between apps. See the bug for more details.
Note: this backport does not include the OBSCURED option since its
not needed for the security fix.
