Muting node patch: second part. Also fix [#27636] Muting shading nodes is ignored

Now, compositing, shading and texture nodes have a consistent muting system, with default behaving as previous (for compo), and which can be optionaly customized by each node.
Shader nodes are also GLSL muted.

However, Cycles is currently unaware of muted nodes, will try to address this…
