Fix Imaginate by porting its JS roundtrip code to graph-based async execution in Rust (#1250)

* Create asynchronous rust imaginate node

* Make a first imaginate request via rust

* Implement parsing of imaginate API result image

* Stop refresh timer from affecting imaginate progress requests

* Add cargo-about clarification for rustls-webpki

* Delete imaginate.ts and all uses of its functions

* Add imaginate img2img feature

* Fix imaginate random seed button

* Fix imaginate ui inferring non-custom resolutions

* Fix the imaginate progress indicator

* Remove ImaginatePreferences from being compiled into node graph

* Regenerate imaginate only when hitting button

* Add ability to terminate imaginate requests

* Add imaginate server check feature

* Do not compile wasm_bindgen bindings in graphite_editor for tests

* Address some review suggestions

- move wasm futures dependency in editor to the future-executor crate
- guard wasm-bindgen in editor behind a `wasm` feature flag
- dont make seed number input a slider
- remove poll_server_check from process_message function beginning
- guard wasm related code behind `cfg(target_arch = "wasm32")` instead
  of `cfg(test)`
- Call the imaginate idle states "Ready" and "Done" instead of "Nothing
  to do"
- Call the imaginate uploading state "Uploading Image" instead of
  "Uploading Input Image"
- Remove the EvalSyncNode

* Fix imaginate host name being restored between graphite instances

also change the progress status texts a bit.
