Introduce esbuild on webpack (#14578)

* Vendor node mods as cache; fix esbuild/fomantic offline build

* Fix --exclude; use bsdtar for consistent globbing

* Fall back to GNU tar; forward-compatible for APT 2.0

* Avoid having extd. attrs with bsdtar

* Dependency and misc. optimizations

* Remove extra code after esbuild-loader update
