feat(@schematics/angular): directly use @angular/build in new projects

The `@angular/build` package is now used directly within all newly created
projects and replaces the previous usage of the `@angular-devkit/build-angular`
package. This has the advantage of removing the need to install all of the
Webpack related transitive dependencies contained within `@angular-devkit/build-angular`
that are used to support the `browser` builder. This results in a significant
reduction in both total dependency count and disk install size for new projects.
New projects that would prefer to use the Webpack-based `browser` builder can still
install the `@angular-devkit/build-angular` package within the workspace.

The `@angular/build@19.2.0-next.2` package currently has a total unpacked size of ~115 MB.
The `@angular-devkit/build-angular@19.2.0-next.2` package currently has a total unpacked size of ~291 MB.
