Avoid elevating apps to high proc states on binding

For service and provider bindings from TOP and
FOREGROUND_SERVICE apps, don't elevate bound apps
to above BOUND_FOREGROUND_SERVICE.

For service bindings, it is possible to explicitly
request the binding to match the foreground app
such that the bound app can get similar privileges
of foreground permissions.

For instance, when a foreground service has a location
type, providers it binds to don't automatically get the
location privilege. On the other hand, sometimes apps
showing UI want to treat their dependencies also as if
they are showing UI.

This change does not affect the oom_adj calculation,
only the proc state calculation for bound processes.

New BIND_INCLUDE_CAPABILITIES flag can be used to restore old
behavior for bound services.

Introduces a new state PROCESS_STATE_BOUND_TOP
