JoostK a6849f27af fix(compiler-cli): evaluate const tuple types statically (#48091)
For standalone components it may be beneficial to group multiple declarations
into a single array, that can then be imported all at once in `Component.imports`.
If this array is declared within a library, however, would the AOT compiler
need to extract the contents of the array from the declaration file. This
requires that the array is constructed using an `as const` cast, which results
in a readonly tuple declaration in the generated .d.ts file of the library:

```ts
export declare const DECLARATIONS: readonly [typeof StandaloneDir];
```

The partial evaluator logic did not support this syntax, so this pattern was
not functional when a library is involved. This commit adds the necessary
logic in the static interpreter to evaluate this type at compile time.

Closes #48089
