Rework wasm initialization and reduce global state (#379)

* wasm: do the async initialization only once

This allows the rest of the app to access wasm synchronously.

This allows removing of a global.

* provide the wasm via vue provide/inject.

There's still code directly accessing the wasm. That will be changed later.

* MenuBarInput: use injected wasm instead of the global instance

* Let the App handle event listeners

* move stateful modules into state/

* state/fullscreen: create per instance

* App: load the initial document list on mount.
This got lost a few commits ago. Now it's back.

* state/dialog: create per instance

* util/input: remove dependency on global dialog instance

* state/documents: create per instance

* reponse-handler: move into EditorWasm

* comingSoon: move into dialog

* wasm: allow instantiating multiple editors

* input handlers: do not look at canvases outside the mounted App

* input: listen on the container instead of the window when possible

* - removed proxy from wasm-loader
- integrated with js-dispatcher
- state functions to classes
- integrated some upstream changes

* fix errors caused by merge

* Getting closer:
- added global state to track all instances
- fix fullscreen close trigger
- wasm-loader is statefull
- panic across instanes

* - fix outline while using editor
- removed circular import rule
- added editorInstance to js message constructor

* - changed input handler to a class
- still need a better way of handeling it in App.vue

* - fixed single instance of inputManager to weakmap

* - fix no-explicit-any in a few places
- removed global state from input.ts

* simplified two long lines

* removed global state

* removed $data from App

* add mut self to functions in api.rs

* Update Workspace.vue

remove outdated import

* fixed missing import

* Changes throughout code review; note this causes some bugs to be fixed in a later commit

* PR review round 1

* - fix coming soon bugs
- changed folder structure

* moved declaration to .d.ts

* - changed from classes to functions
- moved decs back to app.vue

* removed need to export js function to rust

* changed folder structure

* fixed indentation breaking multiline strings

* Fix eslint rule to whitelist @/../

* Simplify strip-indents implementation

* replace type assertions with better annotations or proper runtime checks

* Small tweaks and code rearranging improvements after second code review pass

* maybe fix mouse events

* Add back preventDefault for mouse scroll

* code review round 2

* Comment improvements

* -removed runtime checks
- fixed layers not showing

* - extened proxy to cover classes
- stopped multiple panics from logging
- Stop wasm-bindgen from mut ref counting our struct

* cleaned up messageConstructors exports

* Fix input and fullscreen regressions
