[Physical Keyboard Setting] Update navigation path

When launch setting page for specific keyboard, it will route to PK
setting first, add flag NO_HISTORY to make PK setting not been added in
stack.
So that when user navigate back, it will not back to PK setting,
which will be more consistent.

Update navigation path from:
Device Detail -> Physical Keyboard Setting -> Keyboard Detail Setting
to
Device Detail -> Keyboard Detail Setting
