Expected Behavior

'Custom' ontrol name should be more descriptive, and correct role should be defined. .i.e. For Collapsed 'Custom' control Screen Reader should announce 'Custom Tab Colors button Collapsed' and For Expanded 'Custom' control Screen Reader should announce 'Custom Tab Colors button Expanded'

Actual Behavior

'Custom' control name is not descriptive, and role defined is incorrect. i.e. For Collapsed 'Custom' control Screen Reader should announce 'Custom Button off' and For Expanded 'Custom' control Screen Reader should announce 'Custom Button On'

Observation: Issue repro with NVDA and JAWS Screen Reader.

We're using the ColorPickupFlyout, which is a custom control. So I'm guessing we need to create a custom automation peer for this. I've done this before for the TermControlAutomationPeer, so it shouldn't be difficult to do, just annoying haha. I'm betting this'll close most of the "Terminal > Set tab color" a11y sev3s we have too.

#13552 will "fix" this by removing the "Custom" button entirely.
