feat!: remove webpack-based EdgeBundler in favor of ESBuild

BREAKING CHANGE: The webpack-based EdgeBundler has been removed. All edge
bundling now uses ESBuild via EdgeESBuildBundler. Users must update their
CLI invocations from `--bundler webpack` to `--bundler esbuild`.

- Remove src/EdgeBundler.js
- Remove @adobe/helix-deploy-plugin-webpack peer dependency
- Update all tests to use esbuild bundler
- ESBuild provides faster bundling with smaller output
