NLL migrate mode: issues two errors for move out of single static item

[pnkfelix]

This code (play)

struct S;
pub fn main() {
    let _y = { static x: S = S; x };
}

issues the following diagnostics under migrate mode:

error[E0507]: cannot move out of static item
 --> src/main.rs:3:33
  |
3 |     let _y = { static x: S = S; x };
  |                                 ^
  |                                 |
  |                                 cannot move out of static item
  |                                 help: consider borrowing here: `&x`

error[E0507]: cannot move out of immutable static item `x`
 --> src/main.rs:3:33
  |
3 |     let _y = { static x: S = S; x };
  |                                 ^
  |                                 |
  |                                 cannot move out of immutable static item `x`
  |                                 cannot move

error: aborting due to 2 previous errors

It issues only a single error under either of AST-borrowck or pure NLL.

(This is obviously one particular instance of #53004)

This should be fixed by PR #55221
