Add support for CI screenshot testing

Rework the high-level App & AppView widgets a bit to allow
conditionally displaying a simple fixed pattern if the
HOMESCREEN_DEMO_CI environment variable is set to anything
other than "0".  The pattern displayed matches what the
Qt homescreen shows for this to allow the CI test to be
common.

Bug-AGL: SPEC-5203
