meson: Add an option to disable gst-full

Not all static-library build configurations need to use this, and the
CPU time and RAM needed by gst-full targets is quite significant.

+Since 1.24.7, it is possible to disable the `gstreamer-full` library by passing
+`-Dgst-full=disabled`. This can be useful in cases where you want a static
+build of gstreamer, but you do not want to use gst-full, since linking the
+static executables associated with it can be quite CPU/RAM intensive.
