gstreamer: Add common .inc files for meson based recipes

* gstreamer1.0-plugins-common.inc
  The old gstreamer1.0-plugins.inc file, adapted for meson
* gstreamer1.0-plugins-packaging.inc
  The old gst-plugins-package.inc file, adapted for meson
* gstreamer1.0-ptest.inc
  Common code for meson based PTest support; autogenerates the run-ptest
  file and is designed to use the gnome-desktop-testing suite runner
  (which is why the .inc files inherits from ptest-gnome)

(From OE-Core rev: 075aa7a617d38d6a698cee97dcb7550e72741eb5)
