Implement accessibility detailed view for the MD Ash system menu

Introduced a new layout for accessibility detailed view. Each row now
contains a vectorized icon which is shown on left, a description which
is shown in the middle and a check mark is shown on the right. The row
on the bottom which contains "setting" option and "learn more" option
is removed and it will be included in the title row in the future cls.

This CL also updates the description of ChromeVox from "ChromeVox (Spoken
feedback)" to "ChromeVox (spoken feedback)"
