build: update beasties to 0.5.1

Updates Beasties to version 0.5.1 and simplifies the inline critical CSS
implementation in @angular/build and @angular/ssr by using Beasties'
native preload: 'media-script' and nonce callback support.

Additionally, refactors `inlineCriticalCss` in @angular/build into a
standalone function and relocates `InlineCriticalCssProcessor` into
@angular-devkit/build-angular for Webpack-based builders.
