As reported in #20113, webpack triggers a Trusted Types violation when
lazy-loading is used. To mitigate that, enable webpack's Trusted Types
module (introduced in webpack/webpack#9856) using 'angular#bundler' as
the policy name.
The Worker constructor option for a transfer list is unfortunately not supported until Node.js 12.17. For Node.js versions prior to 12.17, a manual message post is now used to transfer the necessary initialization data to the Sass workers.
AJV only support a single schema with the same ID, compiling schemas async can cause a race condition were multiple schemas with the same name as compiled at the same time.
Closes#20847
This reduce memory consumption during re-builds.

A pool of Workers is now used to process Sass render requests. This change allows multiple synchronous render operations to occur at the same time. Sass synchronous render operations can be up to two times faster than the asynchronous variant. The benefit will be most pronounced in applications with large amounts of Sass stylesheets.
The dart-sass Sass implementation will now be executed in a separate worker thread. The wrapper worker implementation provides an interface that can be directly used by Webpack's `sass-loader`.
The worker implementation allows dart-sass to be executed in its synchronous mode which can be up to two times faster than its asynchronous mode. The worker thread also allows Webpack to continue other bundling tasks while the Sass stylesheets are being processed.
This change allows consumers of the `NodeWorkflow` to configure the package installation task to use a package manager's `--force` option. This will be used by the `@angular/cli` update command when the update command's force option is used. This change is not intended to enable a schematic to adjust the force option.
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
