media-libs/gstreamer: Bump to 1.20.0

Gstreamer 1.20.0 version bump, includes
- all existing 1.18.4 plugins except for two dropped upstream
  (gst-plugins-libmms and gst-plugins-ofa)
- libnice-0.1.18 version bump required by gst-plugins-webrtc in 1.20.0
- required multilib change for libldac for new plugin gst-plugins-ldac
- required multilib change for libopenaptx and libfreeaptx for new plugin
  gst-plugins-openaptx

As discussed, this change adds a LICENSE to each of gstreamer modules which
now require explicit opt-in for (A)GPL plugins for (A)GPL plugins we will not
perform explicit license acceptance for affected gstreamer plugin, instead we
will rely on a user accepting the license of dependency:
- gstreamer change added explicit opt-in https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1084
- I looked at affected gstreamer plugins and looks like all are correctly
  license-compatible according to compatibility matrix https://www.gnu.org/licenses/gpl-faq.html#AllCompatibility
- if a user is not willing to accept the license of corresponding (A)GPL
  dependency, such dependency will not be available and affected gstreamer
  plugin will not be built
- Upstream gstreamer team will look into updating/fixing plugin license display
  available via gst-inspect-1.0 <plugin name> | grep License as currently it is
  just "GPL" which is not specific enough (should be GPL-2, GPL-2+, GPL-3 etc.)
