Auto merge of #81346 - hug-dev:nonsecure-call-abi, r=jonas-schievink
Add a new ABI to support cmse_nonsecure_call This adds support for the `cmse_nonsecure_call` feature to be able to perform non-secure function call. See the discussion on Zulip [here](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/Support.20for.20callsite.20attributes/near/223054928). This is a followup to #75810 which added `cmse_nonsecure_entry`. As for that PR, I assume that the changes are small enough to not have to go through a RFC but I don't mind doing one if needed 😃 I did not yet create a tracking issue, but if most of it is fine, I can create one and update the various files accordingly (they refer to the other tracking issue now). On the Zulip chat, I believe `@jonas-schievink` volunteered to be a reviewer 💯
