Pete Bacon Darwin ec9f4d5bc6 perf(ngcc): use the EntryPointManifest in DirectoryWalkerEntryPointFinder (#35931 )

The `DirectoryWalkerEntryPointFinder` has to traverse the
entire node_modules library everytime it executes in order to
identify the entry-points that need to be processed. This is
very time consuming (several seconds for big projects on
Windows).

This commit changes the `DirectoryWalkerEntryPointFinder` to
use the `EntryPointManifest` to store the paths to entry-points
that were found when doing this initial node_modules traversal
in a file to be reused for subsequent calls.

This dramatically speeds up ngcc processing when it has been run once
already.

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.

Building

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
