Rollup merge of #103277 - thomcc:bump-libc-135, r=Mark-Simulacrum

Update libstd's libc to 0.2.135 (to make `libstd` no longer pull in `libiconv.dylib` on Darwin)

This is to pull in rust-lang/libc#2944.

It's related to rust-lang/rust#102766, in that they both remove unused dylibs from libstd on Darwin platforms. As a result, I'm marking this as relnotes since everybody agreed it was good to add it to the other as well. (The note should be about no longer linking against libiconv -- the libc update is irrelevant).

Might as well have the same reviewer too.
