Introduce wildcard const for FixedSizeBinary

### Is your feature request related to a problem or challenge?

Original discussion: https://github.com/apache/datafusion/pull/17179#discussion_r2289772160

It's hard to specify a type signature that includes an arbitrarily sized `FixedSizeBinary` as would need to specify each and every size; ideally would be solved by a wildcard, similar to how it's handled for `FixedSizeList`:

Wildcard:

https://github.com/apache/datafusion/blob/f363e382661a4f45dad2912e9988f1703e46939b/datafusion/expr-common/src/signature.rs#L41-L44

How wildcard is used:

https://github.com/apache/datafusion/blob/f363e382661a4f45dad2912e9988f1703e46939b/datafusion/expr/src/type_coercion/functions.rs#L877-L889

### Describe the solution you'd like

Introduce a wildcard const for `FixedSizeBinary` to use during coercion

### Describe alternatives you've considered

_No response_

### Additional context

Fix any type signatures that use `FixedSizeBinary` to use this new wildcard, for example in #17179 code

	/// Constant that is used as a placeholder for any valid fixed size list.
	/// This is used where a function can accept a fixed size list type with any
	/// valid length. It exists to avoid the need to enumerate all possible fixed size list lengths.
	pub const FIXED_SIZE_LIST_WILDCARD: i32 = i32::MIN;

	// should be able to coerce wildcard fixed size list to non wildcard fixed size list
	(
	FixedSizeList(f_into, FIXED_SIZE_LIST_WILDCARD),
	FixedSizeList(f_from, size_from),
	) => match coerced_from(f_into.data_type(), f_from.data_type()) {
	Some(data_type) if &data_type != f_into.data_type() => {
	let new_field =
	Arc::new(f_into.as_ref().clone().with_data_type(data_type));
	Some(FixedSizeList(new_field, *size_from))
	}
	Some(_) => Some(FixedSizeList(Arc::clone(f_into), *size_from)),
	_ => None,
	},
