Feature: UI Toolkit support

[Luca3317]

Is your feature request related to a problem? Please describe.
Right now TMPEffects only supports texts created by TextMeshPro (=> TMP_Text components) in the UGUI system.

Describe the solution you'd like
Also support UI Toolkit texts.
Since UI Toolkit uses TextCore, which is based on TextMeshPro, this might be possible without needing entire rewrites.

Additional context
At the moment this does not seem possible to implement, since UI Toolkit doesnt offer any way to access text's mesh data.

It looks like they added the required hooks for this around 6.1 or 6.2 finally!
I am transitioning a lot of my game's UI to UITK currently, so while I'm likely going to stick to a self-rolled solution, I've used yours (and still am in parts of my projects) with great success before, so I thought I'd let you know.

Thank you for making this amazing tool!
