Rollup merge of #128348 - dingxiangfei2009:allow-shadow-call-stack-sanitizer, r=tmandry
Unconditionally allow shadow call-stack sanitizer for AArch64

It is possible to do so whenever `-Z fixed-x18` is applied.

cc ``@Darksonn`` for context

The reasoning is that, as soon as reservation on `x18` is forced through the flag `fixed-x18`, on AArch64 the option to instrument with [Shadow Call Stack sanitizer](https://clang.llvm.org/docs/ShadowCallStack.html) is then applicable regardless of the target configuration.

At the every least, we would like to relax the restriction on specifically `aarch64-unknonw-none`. For this option, we can include a documentation change saying that users of compiled objects need to ensure that they are linked to runtime with Shadow Call Stack instrumentation support.
