Export GES library API in headers when we're building the library itself, otherwise import the API from the headers. This fixes linker warnings on Windows when building with MSVC. Fix up some missing config.h includes when building the lib which is needed to get the export api define from config.h Fixes https://gitlab.freedesktop.org/gstreamer/gst-editing-services/issues/42
