Clients of exo expects to handle the key repeat in the client side
according to crrev.com/c/1079768.
Therefore, exo::Keyboard silently ignores the key repeat events.
However, it doesn't mark the key repeat events as handled and
they are used to invoke the accelerators.
This CL changes exo::Keyboard to mark the key repeat events as handled,
then they are not used to invoke the accelerators anymore.

Bug: b/149477038
Test: Hold Ctrl and W on an ARC++ app which eats Ctrl-W key event, and
check that the app doesn't close.
