core/wayland: thread-safety meta fixes + cleanups + hypr workaround

- fork go-wayland/client and modify to make it thread-safe internally
- use sync.Map and atomic values in many places to cut down on mutex
  boilerplate
- do not create extworkspace client unless explicitly requested

+# Wayland implementation in Go
+
+[![Go Reference](https://pkg.go.dev/badge/github.com/AvengeMedia/DankMaterialShell/core/pkg/go-wayland/wayland.svg)](https://pkg.go.dev/github.com/AvengeMedia/DankMaterialShell/core/pkg/go-wayland/wayland)
+
+This module contains pure Go implementation of the Wayland protocol.
+Currently only wayland-client functionality is supported.
+
+Go code is generated from protocol XML files using
+[`go-wayland-scanner`](cmd/go-wayland-scanner/scanner.go).
+
+To load cursor, minimal port of `wayland-cursor` & `xcursor` in pure Go
+is located at [`wayland/cursor`](wayland/cursor) & [`wayland/cursor/xcursor`](wayland/cursor/xcursor)
+respectively.
+
+To demonstrate the functionality of this module
+[`examples/imageviewer`](examples/imageviewer) contains a simple image
+viewer. It demos displaying a top-level window, resizing of window,
+cursor themes, pointer and keyboard. Because it's in pure Go, it can be
+compiled without CGO. You can try it using the following commands:
+
+```sh
+CGO_ENABLED=0 go install github.com/AvengeMedia/DankMaterialShell/core/pkg/go-wayland/examples/imageviewer@latest
+
+imageviewer file.jpg
+```
