Based on emilk/egui#3824

* chore: fix more update-induced errors

* chore: remove DX12 push constants workaround (fixed in wgpu 0.19)

* feat: web build now has WebGPU and WebGL support in one binary

* fix: make eframe's secure context check use worker context

* chore: write upstream eframe and egui-wgpu version as 0.25.0

Chances are when the wgpu update changes land into a stable release of
egui, they're going to use a squash merge, so we have no choice but to
use commits from the egui master branch as the base commits for merges.

* chore: update Trunk to latest version

* chore: remove unnecessary dependency on glow

* chore: remove assets/webgpu-test-worker.js

* refactor: use relative public path

This allows easily serving Luminol web builds under any path (e.g.
https://example.com/luminol/ instead of https://example.com/).
