Look into replacing Webpack with esbuild

[wkillerud]

The VS Code extension generator now has an option to use esbuild. There are samples and docs that explain the setup.

The webpack build is fairly slow, so I'd be interested to see if it can be replaced with esbuild to speed things up a bit.

• esbuild-sample
• Web extensions: esbuild
• Extensions: esbuild

Webpack is used both in the language server and the extension modules:

• https://github.com/wkillerud/some-sass/tree/main/packages/language-server
• https://github.com/wkillerud/some-sass/tree/main/vscode-extension

I had quite success with the speed of build, when I've set cache from memory to filesystem. Maybe you can take a look :)
