FormTokenField: handle disabled prop on internal Button

[chad1008]

replaces #23713

What?

Pass the disabled prop to the Button component on selected tokesn

Why?

When FormTokenField is disabled, the buttons don't remove tokens because the click isn't handled. The buttons are still focusable though, which isn't ideal.

How?

prop forwarding

Testing Instructions

1. Launch Storybook and test the Default FormTokenField story
2. Select a couple of options
3. In the Controls panel, set Disabled to true
4. Confirm that the tokens you've added cannot be removed, and clicking on the x button doesn't apply focus.

I was initially going to say it feels weird to include the 'remove' buttons at all if the control is disabled, but actually that feels more like read-only behaviour. So 🚀 – works for me.
