What I did
Probe the DASH resource only when run on the DPU.
Why I did it
The changes optimize the CRM Orch to not access the DASH resources when it is clear that the device running the SONiC doesn't support them.
Also this prevents potential SAI library incompatibility caused by SAI metadata changes introduced in opencomputeproject/SAI#2028 PR
How I verified it
Run CRM UT.
