Dropping Globe plugin from the QGIS sources. It depends on osgearth no
newer than version 2.8, released on 2016-09-05, and which is impossible

optional QGIS dependency on OpenSceneGraph and osgearth is also removed.
[infrastructure] [macos] use QGIS-Mac-Packager dependencies to setup MacOS CI build with GitHub workflows. Use CMake's define QGIS_MAC_DEPS_DIR to define folder to dependencies
