[AMDGPU] Add DAG mutation to improve scheduling before barriers (#142716)
Add scheduler DAG mutation to add data dependencies between atomic
fences and preceding memory reads. This allows some modelling of the
impact an atomic fence can have on outstanding memory accesses.
This is beneficial when a fence would cause wait count insertion, as
more instructions will be scheduled before the fence hiding memory
latency.
