Fix: ToggleButton accessibility attributes

[tneeraja95]

Fix #8021

Fixes -

1. Added aria-label and aria-labelledby from props to the ToggleButton input for accessible naming.
2. Removed role and aria-pressed from the input element, as they are not applicable to type="checkbox" and can create conflicting semantics.
