[Wi-Fi] [a11y] The "Advanced options" should be accessible by Voice Access and pronounced by talkback correctly.

Browse Source 
The checkbox is unclickable via Accessibility.

Solution: Refine the solution of b/30079196 to let checkbox be focusable and clickable by Accessibility, and remove unnecessary Accessibility pronunciation strings.

Bug: 141588638
Bug: 141588161
Test: Add unit test to check the content description of the checkbox.
