[Feature] Add a mechanism to persist the content hover size

Add the possibility to persist the content hover sizes

[aiday-mar]

To test, please read the following.

Currently the implementation of the persistance mechanism of the content hover works as follows:

---

The content hover has a default maximum size which is defined as follows:

const defaultMaxHeight = Math.max(this._editor.getLayoutInfo().height / 4, 250);
const defaultMaxWidth = Math.max(this._editor.getLayoutInfo().width * 0.66, 500);

Whenever the content hover is resized, the last hover dimensions are stored. Next time the content hover is shown, the maximum dimensions are updated as follows:

const currentMaxHeight = Math.max(this._editor.getLayoutInfo().height / 4, 250, lastHeight);
const currentMaxWidth = Math.max(this._editor.getLayoutInfo().width * 0.66, 500, lastWidth);

The content hover is rendered naturally within these constraints. If the lastHeight and lastWidth are smaller than the default max dimensions, then the current max dimensions are unchanged. Therefore the next rendering of the content hover will be the same as the initial rendering.

---

Test that the content hover works according to these constraints. There is some discussion going on about how to better implement a persistance mechanism. We could also persist the size for example on a per-token basis in the editor. Let me know what you think is best!

Do you have an example of how it should work? Regardless of how I resize it, it is not remembered.

You may see an example of how it works here. The content hover is resized to a bigger size in the gif. The current max width is increased to a higher value and at the next rendering of the content hover, the widget takes on a bigger size. To see this behavior you should choose a content hover where the content does not fit in the visible widget, where there is a horizontal scrollbar.

I opened an issue for persisting the content hover on a per-token basis here: #187904 as an alternative idea.
