Approach

What is the motivation for this PR?

To update test_voq_fabric_capacity to match the expanded fabric capacity
CLI (Isolated Links column) and new ISOLATE_REASON field in fabric
isolation output.

How did you do it?

Validate both operating_links and isolated_links after config isolate
and unisolate, and verify the isolated port reports isolate reason
"config" via "show fabric isolation -nz".

Run on fabric cards using enum_rand_one_per_hwsku_hostname, pick ASICs
from asics_present

How did you verify/test it?

Tested on a multi Asics multi LCS chassis platform

Any platform specific information?

Supported testbed topology if it's a new test case?
