Disables the injectable pipe migration until we can decide whether this is the right solution for Ivy. Rolling it out properly will involve a more detailed plan and more changes like updating the styleguide, scaffolding schematics etc.
Context for the new `test-migrations.json`: since we use the `migrations.json` both for the real migrations and for tests, it doesn't allow us to disable a schematic, but continue running its tests. This change adds the test-specific file so that we can continue running the `injectable-pipe` tests, even though the schematic itself is disabled.

While running `ng update @angular/core --next`, the following error would be displayed:
```
Cannot find module '....\node_modules\@angular\core\schematics\migrations\template-var-assignment\index'
```
This happened because the Schematics migration was referenced, but not included.
This commit fixes that bug by including the migration in the Bazel npm package dependencies.
PR Close#29705
Introduces an update schematic for the "@angular/core" package
that automatically migrates pre-V8 "ViewChild" and "ContentChild"
queries to the new explicit timing syntax. This is not required
yet, but with Ivy, queries will be "dynamic" by default. Therefore
specifying an explicit query timing ensures that developers can
smoothly migrate to Ivy (once it's the default).
