[FIX]: Speed up Angular Vite Plugin

[brandonroberts]

The initial implementation of the Vite Plugin for Angular builds on the POC done by the browser builder for esbuild in the Angular CLI. This doesn't take into account for watch mode, and doesn't do much caching or incremental analysis.

I ported over some of the incremental analysis from the @ngtools/webpack AngularWebpackPlugin, but more could be done here to make it fast enough. Incremental analysis is the closest we'll get to single file compilation until its supported in Angular.
