[canvas] Improve plugin pre-build (#25267) (#25569)
Fixes https://github.com/elastic/kibana/issues/23552

Extends the webpack config used to pre-build `x-pack/plugins/canvas/canvas_plugins_src` so that it does a couple things:
 - use the "browser" and "main" fields when defined by packages, this allows the already transpiled output of packages like `@elastic/eui` to be used rather than rebuilding from source
 - use the `@kbn/babel-preset/webpack_preset` for babel-loader
 - include all errors in the log output when an error occurs
