type alias impl trait: add tests showing that hidden type only outlives lifetimes that occur in bounds

fixes rust-lang#103642

rust-lang#102417 only made sure that hidden types cannot outlive lifetimes other than the ones mentioned on bounds, but didn't allow us to actually infer anything from that.

Don't use periods in target names

Using a period in the target name can cause issues in e.g. cargo, see also https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/Running.20tests.20on.20remote.20target

Print all features with --print target-features

This fixes `rustc --print target-features` with respect to aliases and tied features.

Before this change, the print command assumed that each LLVM feature corresponds exactly to one rustc feature.  In the case of aliases and tied features, this assumption failed and some features (such as aarch64's "pacg") were missing.  With this change, every target feature is listed.

Run patchelf also on rust-analyzer-proc-macro-srv.

On NixOS, `rust-analyzer-proc-macro-srv` needs to be `patchelf`ed just like all the other libs and binaries.

With this fix, I am able to use the language server configuration recommended in [the guide](https://rustc-dev-guide.rust-lang.org/building/suggested.html#configuring-rust-analyzer-for-rustc).
