Revamp the syntax to #[hard(a..b)] and #[soft(a..b)] bounds on node definitions (#4307)

* Revamp the syntax to #[hard(a..b)] and #[soft(a..b)] bounds on node definitions

* Address review feedback: error on empty bounds ranges and remove redundant count clamps

* Fix NaN transform from Repeat Array with a count of 1

* Remove redundant manual clamps already enforced by #[hard(...)] bounds

+The macro invocation can be extended with additional attributes. The currently supported attributes are (`name`, `path`, `skip_impl`, `category`). When using generics the `#[implementations()]` attribute can be used to automatically populate the node_registry for you. You can also use the `default`, `expose`, `soft`, `hard`, and `range` attributes to influence how the properties are generated. The `#[soft(a..b)]` and `#[hard(a..b)]` attributes set the slider's suggested extent and its enforced clamp, respectively (either endpoint may be omitted, e.g. `0..` or `..100`; both endpoints are inclusive, so there is no `..=` form), and `#[range]` renders the input as a draggable slider. Values typed into the input may exceed the soft extent but are clamped to the hard bounds, so `#[soft]` is only meaningful together with `#[range]`.
