George Kalpakas 772ccf0d9f feat(ngcc): support reverting a file written by FileWriter (#36626)
This commit adds a `revertFile()` method to `FileWriter`, which can
revert a transformed file (and its backup - if any) written by the
`FileWriter`.

In a subsequent commit, this will be used to allow ngcc to recover
when a worker process crashes in the middle of processing a task.

Angular Compatibility Compiler (ngcc)

This compiler will convert node_modules compiled with ngc, into node_modules which appear to have been compiled with ngtsc.

This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.

The project is built using Bazel:

yarn bazel build //packages/compiler-cli/ngcc

Unit Testing

The unit tests are built and run using Bazel:

yarn bazel test //packages/compiler-cli/ngcc/test

Integration Testing

There are tests that check the behavior of the overall executable:

yarn bazel test //packages/compiler-cli/ngcc/test:integration
