Show String properties' text in a tooltip in the inspector

[Calinou]

This allows previewing single-line or multipline strings that are too long too fit within the box in the inspector.

I wonder if it's possible to only show the tooltip if the text doesn't fully fit within the box. @bruvzg Is there a way we can detect this while taking the font size and advance into account (for both LineEdit and TextEdit)?

• This closes Inspector shoud show a tip to show full property value on Resource-selected godot-proposals#6638.

How does this work with properties that have doc comments?

The value's tooltip is shown when hovering the value. The documentation is only shown when hovering the name, like before. (This also applies to properties of types other than String.)

I don't think that's a necessary complication, all types always show their value as tooltips.

Rebased and tested again, it works as expected.

Moving this to 4.4 as it should've been a long time coming.

I'm not sure if simply displaying everything is a good idea

It needs some sort of autowrapping/scroll.

I've trimmed the tooltip to the first 100 characters, so it should no longer get very long now.

Functionality-wise looks ok.

Thanks!
