The scancodes for the Lang1 and Lang2 keys (i.e. Hangeul, Hanja) are
special since they already have the 0x80 bit set which is commonly used
to indicate a key release in AT set 1. Reportedly, real hardware does
not send a key release scancode. So, skip sending a release for these
keys. This ensures that Windows behaves correctly and interprets it as a
single keypress rather than two consecutive keypresses.
