Rework to use launcher wrapper from libqtappfwneedlefish

Switch to using the new app launcher API wrapper from libqtappfw in
order to migrate to the new gRPC based API implementation.  As well,
the copyright headers in the source files have been tweaked to remove
the Apache license boilerplate in favour of a SPDX license tag.
