Pete Bacon Darwin 78a44768e0 fix(ngcc): ensure lockfile is removed when analyzeFn fails (#37739)
Previously an error thrown in the `analyzeFn` would cause
the ngcc process to exit immediately without removing the
lockfile, and potentially before the unlocker process had been
successfully spawned resulting in the lockfile being orphaned
and left behind.

Now we catch these errors and remove the lockfile as needed.

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.

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

Unit Testing
