Rename Graphene crate structure

- `/node-graph/libraries` -> `/node-catalog/types`
- `/node-graph/nodes` -> `/node-catalog/nodes`
- `/node-graph` -> `/graphene`
- `/node-graph/graph-craft` -> `/graphene/compiler`
- `/node-graph/graphene-cli` -> `/graphene-cli`
- `/node-graph/interpreted-executor` -> `/graphene/interpreter`
- `/node-graph/node-macro` -> `/graphene/macros`
- *Call this crate `graphene-macros`*
- *Use a prelude to turn `#[node_macro::node(...)]` into `#[node(...)]`*
- `/proc-macros` -> *split apart into:*
- `/editor/macros` *(message system)*
- *Call this crate `editor-macros`*
- `/graphene/macros` (widget builder)
- `/frontend/wasm` -> `/frontend/wrapper` (Done: #3927)

*Also: update the special casing and terminology in `/tools/crate-hierarchy-viz` code.*
