[libc][NFC] Add -Wno-multi-gpu everywhere for the GPU build (#83173)

Browse Source 
Summary:
This warning is intended to indicate if `-march=native` returns
different values in a single compilation sense. As it stands we don't
care and it absolutely spams the test output if you run it on a machine
with more than one GPU like any cluster machine. Disable these warnings
everywhere we compile.
