Auto merge of #109335 - Mark-Simulacrum:stable-next, r=Mark-Simulacrum 1.68.1

[stable] 1.68.1 release

This packages up a set of release notes, version bump, and backports of:

* Don't eagerly convert principal to string #108162
*  Revert "enable ThinLTO for rustc on x86_64-pc-windows-msvc dist builds" #109094
*  Create dirs for build_triple #109111
*  Fix linker detection for clang with prefix #109156
*  ci: use apt install --download-only for solaris debs #108951

The last of those is not yet stable-accepted but I expect it to be, we will drop it and rebuild artifacts if we don't actually approve it.
