  [Clang] Do not emit multi-gpu warning if they are all the same (#185490)

Summary:
This warning exists because if you do `-mcpu=native` in some contexts it
may not be obvious which GPU you get. But if they are all the same then
it really don't make a difference since we just pass the first one to
`-mcpu` anyway. Relax this so it doesn't annoyingly warn on machines
with more than one of the same GPU.
