Rollup merge of #127814 - folkertdev:c-cmse-nonsecure-call-error-messages, r=oli-obk

`C-cmse-nonsecure-call`: improved error messages

tracking issue: #81391
issue for the error messages (partially implemented by this PR): #81347
related, in that it also deals with CMSE: https://github.com/rust-lang/rust/pull/127766

When using the `C-cmse-nonsecure-call` ABI, both the arguments and return value must be passed via registers. Previously, when violating this constraint, an ugly LLVM error would be shown. Now, the rust compiler itself will print a pretty message and link to more information.
