[libcxx-commits] [libcxx] [libc++][test] Fix MSVC warnings with `static_cast`s (PR #74962)

[Mark de Wever via libcxx-commits]

I feel that some of these places don't really warrant a compiler diagnostic, but I don't feel the static_casts make it too ugly. I expect this will regress on libc++'s side, not sure what to do about that. Just a remark not something we need to fix.

LGTM
