  [Offload][AMDGPU] Only allow memory pool access to valid agents (#93969)

Summary:
The logic since the next-gen plugins was added was that every single
agent would get access to a memory pool we allocated. This is necessary
for things like fine-grained memory and to faciliate d2d copied.
However, there are cases where an agent cannot legally access a memory
pool. We have a debug check for this, but it would always be triggered
in these situations because both uses of the function simply passed
every agent. This patch changes the behavior by only enabling memory
pool access for agents that can access the memory pool.
