Error encountered when trying to load a GPU backend Atomix extension

I'm not familiar enough with precompilation to know if that's a Julia bug or a bug in this PR.

Tests still seem to pass though...

This error doesn't seem to be present in 1.10 with JuliaLang/julia#55910 backported

[topolarity]

that's a Julia bug

It is. I am seeing this issue on both the latest 1.10 (w/ Pkg backport) and 1.11 backports branches

It should be fixed by JuliaLang/julia#56666
