hasKeycodeLocked() also checks usage codes

Key map can use both scan code and usage code.
Adding usage code check to avoid misjudgment.

Bug: 275526611
Test:
In Android TV, pairing a BT RCU with keylayout which
has usage page/id for DPAD. In PlayStore app search
box, make sure user can move focus to search result
by pressing dpad DOWN key.
