refactor(migrations): ensure CommonJS migrations can be accessed (#43657) The `@angular/core` migrations are currently published as CommonJS and also not bundled. Schematics, of which migrations are a type, are currently required to be CommonJS modules due to the Schematics Runtime not yet supporting ESM-based schematics. To ensure that the migration files are loaded as CommonJS modules, a nested `package.json` file has been introduced within the `schematics` directory of the package to set the `type` field for all containing JavaScript files as CommonJS. Since the migrations are also not currently bundled and the `devmode` output used to build the migrations will replace all relative imports with fully-qualified module specifiers, an additional `exports` entry must be added to allow the fully-qualified module specifiers to correctly resolve. If `devmode` did not change the relative imports the additional entry would not be needed. Bundling would also remedy the situation and is the long-term path, especially once the migrations are converted to ESM. Additional followup changes should investigate bundling each migration. The additional `exports` entry should be removed if either `devmode` behavior is changed or the migrations are bundled. PR Close #43657 2021-10-04 12:03:19 -04:00			`{`
