Remove Autotools build system

Tracker issue for the Autotools build system removal

The purpose of this issue is to track progress and tasks related to removing Autotools as a build system in GStreamer in favour of the Meson build system.

It is not to discuss the pros and cons of doing this or the timing of doing this.

This completes a journey started more than four years ago.

So long, and thanks for all the fish libtool, Autotools!
