Fix navbar editor for RTL layouts.

Remove navigation bar layout XML override which wasn't needed anyway, as
the views in mid_navigation_bar are already reordered based on the
layout direction anyway.

Core: Improve AOSP JA translation

They translated "hotspot" as "アクセスポイント"(access point) but it just gets us confused.
"テザリング"(Tethering) is preferred than "アクセスポイント"(access point) in Japanese translation.
FYI, most vendors fixed these strings e.g. Samsung and Sony.
