fix(@angular-devkit/schematics): remove lazy imports in node tasks

This commit replaces lazy imports with static imports in the node tasks of `@angular-devkit/schematics`.
This change fixes an issue where migrations could fail during an update process if the package layout changes on disk (e.g. due to `npm` hoisting changes) after the main module is loaded but before the lazy chunks are requested. By using static imports, we ensure all necessary code is loaded upfront.

Closes #31974

(cherry picked from commit 98e10fa)
