Rollup merge of #128305 - folkertdev:asm-parser-unsupported-operand, r=Amanieu 
improve error message when `global_asm!` uses `asm!` operands

follow-up to https://github.com/rust-lang/rust/pull/128207

what was

```
error: expected expression, found keyword `in`
 --> src/lib.rs:1:31
  |
1 | core::arch::global_asm!("{}", in(reg));
  |                               ^^ expected expression
```

becomes

```
error: the `in` operand cannot be used with `global_asm!`
  --> $DIR/parse-error.rs:150:19
   |
LL | global_asm!("{}", in(reg));
   |                   ^^ the `in` operand is not meaningful for global-scoped inline assembly, remove it
```

the span of the error is just the keyword, which means that we can't create a machine-applicable suggestion here. The alternative would be to attempt to parse the full operand, but then if there are syntax errors in the operand those would  be presented to the user, even though the parser already knows that the output won't be valid. Also that would require more complexity in the parser.

So I think this is a nice improvement at very low cost.
