[libc] Change the starting port index to use the SMID (#79200)
Summary:
The RPC interface uses several ports to provide parallel access. Right
now we begin the search at the beginning, which heavily contests the
early ports. Using the SMID allows us to stagger the starting index
based off of the cluster identifier that is executing the current warp.
Multiple warps can share an SM, but it will guaruntee that the
contention for the low indices is lower.
This also increases the maximum port size to around 4096, this is
because 512 isn't enough to cover the full hardare parallelism needed to
guarantee this doesdn't deadlock.
