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.)

+# For OpenGL we have three separate concepts, with a list of possibilities in each:
+#  * opengl APIs - opengl and/or gles2; USE=opengl and USE=gles2 enable these accordingly; if neither is enabled, OpenGL helper library and elements are not built at all and all the other options aren't relevant
+#  * opengl platforms - glx and/or egl; also cgl, wgl, eagl for non-linux; USE="X opengl" enables glx platform; USE="egl" enables egl platform. Rest is up for relevant prefix teams.
+#  * opengl windowing system - x11, wayland, win32, cocoa, android, viv_fb, gbm and/or dispmanx; USE=X enables x11 (but for WSI it's automagic - FIXME), USE=wayland enables wayland, USE=gbm enables gbm (automagic upstream - FIXME); rest is up for relevant prefix/arch teams/contributors to test and provide patches
+# With the following limitations:
+#  * If opengl and/or gles2 is enabled, a platform has to be enabled - x11 or egl in our case, but x11 (glx) is acceptable only with opengl
+#  * If opengl and/or gles2 is enabled, a windowing system has to be enabled - x11, wayland or gbm in our case
+#  * glx platform requires opengl API
+#  * wayland, gbm and most other non-glx WSIs require egl platform
+# Additionally there is optional dmabuf support with egl for additional dmabuf based upload/download/eglimage options;
+#  and optional graphene usage for gltransformation and glvideoflip elements and more GLSL Uniforms support in glshader;
+#  and libpng/jpeg are required for gloverlay element;
