This reverts commit 561c0f81a0.
The original commit provided a quick escape from an already terminal
situation by killing the process if the PID in the lockfile was not
found in the list of processes running on the current machine.
But this broke use-cases where the node_modules was being shared between
multiple machines (or more commonly Docker containers on the same actual
machine).

The `Logger` interface and its related classes are general purpose
and could be used by other tooling. Moving it into ngtsc is a more
suitable place from which to share it - similar to the FileSystem stuff.

Currently, if an ngcc process is killed in a manner that it doesn't clean
up its lock file (or is killed too quickly) the compiler reports that it
is waiting on the PID of a process that doesn't exist, and that it will
wait up to a maximum of N seconds. This PR updates the locking code to
additionally check if the process exists, and if it does not it will
immediately bail out, and print the location of the lock file so a user
may clean it up.

When ngcc is having to pause and wait for another process
it provides a message to the user. This commit adds the extra
information about how to remove the lockfile if desired, since
this message is not shown if you Ctrl-C out of the process before
the timeout period ends.

The cached file-system was implemented to speed up ngcc
processing, but in reality most files are not accessed many times
and there is no noticeable degradation in speed by removing it.
Benchmarking `ngcc -l debug` for AIO on a local machine
gave a range of 196-236 seconds with the cache and 197-224
seconds without the cache.
Moreover, when running in parallel mode, ngcc has a separate
file cache for each process. This results in excess memory usage.
Notably the master process, which only does analysis of entry-points
holds on to up to 500Mb for AIO when using the cache compared to
only around 30Mb when not using the cache.
Finally, the file-system cache being incorrectly primed with file
contents before being processed has been the cause of a number
of bugs. For example https://github.com/angular/angular-cli/issues/16860#issuecomment-614694269.

1. update jasmine to 3.5
2. update @types/jasmine to 3.5
3. update @types/jasminewd2 to 2.0.8
Also fix several cases, the new jasmine 3 will help to create test cases correctly,
such as in the `jasmine 2.x` version, the following case will pass
```
expect(1 == 2);
```
But in jsamine 3, the case will need to be
```
expect(1 == 2).toBeTrue();
```

This version of `LockFile` creates an "unlocker" child-process that monitors
the main ngcc process and deletes the lock file if it exits unexpectedly.
This resolves the issue where the main process could not be killed by pressing
Ctrl-C at the terminal.
