  [RFC][AMDGPU] Remove DebugCounter-based WaitCnt debugging

It's 8 years old, only used by a handful of tests, and has not been updated
in a while except for maintenance as far as I can see.

I don't mind keeping it in if there are users of it, but right now it
looks like a dead feature. If we want some more elaborate waitcnt debugging,
we should have a modern, generic system that works on any waitcnt, not
something specific to 3 GFX9 counters.
