Unrolled build for #142682

Rollup merge of #142682 - Gankra:update_musl_1.2.5, r=wesleywiser

Update bundled musl to 1.2.5

Update the bundled musl library from 1.2.3 to the 1.2.5 release from February 29, 2024.

* mcp: rust-lang/compiler-team#887
* blog: rust-lang/blog.rust-lang.org#1641
* Prior update: #107129
* [musl releases page](https://musl.libc.org/releases.html)

--------

This is a rebase of

* #125692

Which removes the second speculative commit which ended up not panning out.

I've added my own second commit that updates all other places I could find that referenced musl 1.2.3 in the codebase.
