Often, the word “identical” when referring to JS objects will
be read as referring to having the same object identity (which is
called “reference equality” here), but what the error message is
trying to say here is that the objects are different but yield the
same `util.inspect()` output.
Since `util.inspect()` output represents the structure rather than
the identity of objects, (hopefully) clarify the error message to
reflect that.

So far consequitive identical lines were collapsed if there were at
least three. Now they are only collapsed from five identical lines on.
This also simplifies the implementation a tiny bit by abstracting some
logic.

In some edge cases an identical line could be printed twice. This is
now fixed by changing the algorithm a bit. It will now verify how
many lines were identical before the current one.

This makes sure long strings as `actual` or `expected` values on an
`AssertionError` won't be logged completely. This is important as
the actual value is somewhat redundant in combination with the error
message which already logs the difference between the input values.

There is only one entry in `kReadableOperator` that ends in `Unequal`.
So the value assigned on line 392 can only be truthy if `operator` is
`notDeepEqual`. Therefore, the ternary condition on line 394 is always
true. Remove the ternary. Coverage reports confirm that the removed code
is unused.

This makes sure that the error message is more appropriate than
before by checking closer what operator is used and which is not.
It also increases the total number of lines printed to the user.

Move lib/internal/assert.js to lib/internal/assert/assertion_error.js.
This is in preparation for making lib/internal/assert.js a tiny module
for use in Node.js built-ins so that we can use `assert()` without
having to load the entire ~1200 line `assert` module.
