Right now the Form component replaces DateTime fields with new Objects, therefore the hash is changing.
This leads to unnecessary database updated when working with doctrine. With this patch the DateTime object
of the actual entity is only replaced if the value has been changed.

[Debug] Fixed recursion level incrementing in FlattenException::flattenArgs().

The internal `$level` variable for tracking the recursion level is pre-incremented on the parent level of the recursion already.

This causes later array elements in an array that has more than 10 elements to get obscured by `'*DEEP NESTED ARRAY*'`, even though the elements are on the first/top level of the array.

The incremented `$level` value needs to be passed to the recursive call to `FlattenException::flattenArgs()` only.

Discovered in debugging exceptions in Drupal (which happens to use very large multi-dimensional arrays for legacy reasons).

This PR fixes #9748 and #9727 by removing the `id` state. Only private method signatures have been changed, so that qualifies for a fix in 2.3.

The `getNotCalledListeners()` is a bit special as it tries to get non-called listeners. It passes `null` as the event id as if a listener has been called more than once, getting the first call is enough.

A possible approach to fix #10204, but I'm open to suggestions to fix this another way, as this might not be the most 'elegant' way.

Initially, my thoughts were to create a new DomCrawler\Field\FormField subclass, especially for image inputs. However, this does not solve the problem, because such a FormField would still exist under 1 name in the FormFieldRegistry.

Instead, I've changed it to have 2 separate FormFields instead (which both reference the same input node), with different names (.x and .y) so that both values can be set separately and will both be submitted.

[DomCrawler] Fixed filterXPath() chaining

| Q             | A
| ------------- | ---
| Bug fix?      | yes
| New feature?  | no
| BC breaks?    | debatable (see below)
| Deprecations? | no

As @stof mentions in #10206, each node in the Crawler can belong to a different \DOMDocument. Therefore, I've made each node do its own XPath, relative to itself, and add all the results to a new Crawler. This way, all resulting nodes are still part of their original \DOMDocument and thus can reach all of their parent nodes.

No current tests break on this change. I've added a new test for this case, by checking if the number of parents is correct after obtaining a node through chaining of `filterXPath()`.

Now for BC: I can think of a number of cases where this change would give a different result. However, it's debatable/unclear if:
- the old behavior was a bug in the first place (which would validate this change), or
- the old behavior was intended (which would make this a BC breaking change)

As an example, consider the following HTML:
```html
<div name="a"><div name="b"><div name="c"></div></div></div>
```
What would happen if we run this:
```php
echo $crawler->filterXPath('//div')->filterXPath('div')->filterXPath('div')->attr('name');
```
Aside from breaking reachability of the parent nodes by chaining, with the original code it would echo 'a'.
With this patch it would echo 'c', which, to me, makes more sense.
