Update resource config for default display

When a launched application doesn't occupy the entire screen space,
there is a mismatch between the configuration of the process and the
configuration of activities. This leads to compatibility issues with
apps that don't expect this, read display metrics from Application
resources and try to apply them in activities.

The platform may apply a compatibility mode, in which the process
configuration will match the config of the top running activity. This
means that the process configuration may change and runtime and
result in display adjustments that are different from the default
values. This CL propagates resource configuration updates even for
default display to make sure that the config changes are reflected
for non-activity contexts.
