Fix generating widget-application item
This commit is based on:
- https://review.tizen.org/gerrit/71796
The way it is changed is:
- widget information is gathered in manifest_x structure and
backend data because data that is created by StepParse is
inserted into database directly according to past changes
(even we add widget information to generated manifest
it is not read).
- icon path is full path for widget-application (same as for
ui-application) to handle icon backup, copying and pkgmgr
expectations.
- <size> is changed to <support-size> defined in manifest.xsd.in
in pkgmgr-info repository.
Requires:
