DomWalkerObservers know about ElementsToRerenderGLOBAL (#6383)

**Problem:**
The dom-walker observers (now used for triggering the dom-sampler) fire
for continuous interactions that don't have
`editor.canvas.interactionSession`, such as scrubbing in the inspector.

**Fix:**
The mutation callback now checks if `ElementsToRerenderGLOBAL.current`
is in selective mode, and then it will behave similarly to when there is
an active interactionSession.

**Commit Details:**

- Renamed `selectCanvasInteractionHappening ` to
`isCanvasInteractionHappening`
- `isCanvasInteractionHappening` is aware of
ElementsToRerenderGLOBAL.current
