Revert "Introduce a new ToggleGraphicsProfiler command (#7607)" (#8567)

This reverts commit 0cebf68306.

Although this thing is very cool, it is a top source of crashes.

Example crash:
```
Segmentation fault: 11 on thread 26
  objc_retain +16
  invocation function for block in Overlay::onCommandBufferCommit(id<MTLCommandBuffer>) +60
  MTLDispatchListApply +52
```

Release Notes:

- Removed "Toggle Graphics Profiler" as it crashes too much.
