Move keyboard event handling into action.c

Since keyboard_layout.[ch] has gained more features, and handles more than just
filling out the keyboard report, move it to action.[ch] instead. I see no sane
way to separate the keyboard and mouse report filling, unless we want to loop
over key states twice, hence them being in the same file.
