Allow tuple structs in animated_field! macro (#17234)

Browse Source 
# Objective

Allow tuple structs in the animated_field macro.
-  for example `animated_field!(MyTupleStruct::0)`.

Fixes #16736 
- This issue was partially fixed in #16747, where support for tuple
structs was added to `AnimatedField::new_unchecked`.

## Solution

Change the designator for `$field` in the macro from `ident` to `tt`.

## Testing

Expanded the doc test on `animated_field!` to include an example with a
tuple struct.
