Kristiyan Kostadinov 1a26f6da6e fix(core): migration error if program contains files outside of the project (#39790)
Currently all of our migrations are set up to find the tsconfig paths within a project,
create a `Program` out of each and migrate the files inside of the `Program`. The
problem is that the `Program` can include files outside of the project and the CLI
APIs that we use to interact with the file system assume that all files are within
the project.

These changes consolidate the logic, that determines whether a file can be migrated,
in a single place and add an extra check to exclude files outside of the root.

Fixes #39778.

ViewEncapsulation.Native migration

Automatically migrates usages of ViewEncapsulation.Native to ViewEncapsulation.ShadowDom. For most practical purposes the Native mode is compatible with the ShadowDom mode.

The migration covers any reference to the Native value that can be traced to @angular/core. Some examples:

  • Inside the encapsulation property of Component decorators.
  • In property assignments for the COMPILER_OPTIONS provider.
  • In variables.

Before

import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  template: '...',
  encapsulation: ViewEncapsulation.Native
})
export class App {
}

After

import { Component, ViewEncapsulation } from '@angular/core';

@Component({
  template: '...',
  encapsulation: ViewEncapsulation.ShadowDom
})
export class App {
}
