[Skia] TextBlock Hyperlinks mouse over / pressed coloring and cursor

[mikernet]

What would you like to be added:

TextBlock on Skia currently does not handle mouse over tracking to allow for hyperlinks to change color and cursor to change to a hand when the mouse is over them. They also don't change color when pressed.

Note that https://github.com/unoplatform/uno/issues/9287 should be done first so that the mouse over / pressed colors can be correctly set from theme resources.

Why is this needed:

User experience and parity with UWP.

For which Platform:

• [ ] iOS
• [ ] Android
• [ ] WebAssembly
• [ ] WebAssembly renderers for Xamarin.Forms
• [ ] macOS
• [X] Skia
  • [ ] WPF
  • [ ] GTK (Linux)
  • [ ] Tizen
• [ ] Windows
• [ ] Build tasks
• [ ] Solution Templates
