input/cmd: add nonscalable prefix 

Some keys like WHEEL_UP are "scaled" if the input source is high
resolution, like touchpad. However, sometimes it's desirable to
disable this scaling and only active the key binding in discrete
steps, such as relative keyframe seeking which interacts poorly
if the command is scaled.

This adds the nonscalable prefix to disable this scaling.

``nonrepeatable``
For some commands, keeping a key pressed runs the command repeatedly.
This prefix forces disabling key repeat in any case.
``nonscalable``
When some commands (e.g. ``add``) are bound to scalable keys associated to a
high-precision input device like a touchpad (e.g. ``WHEEL_UP``), the value
specified in the command is scaled to smaller steps based on the high
resolution input data if available.
This prefix forces disabling this behavior, so the value is always changed
in the discrete unit specified in the key binding.
``async``
Allow asynchronous execution (if possible). Note that only a few commands
will support this (usually this is explicitly documented). Some commands
