input: introduce a pseudo key name that grabs all text input

The intended target for this is the mpv.repl script, which manually
added every single ASCII key as a separate key binding. This provides a
simpler mechanism, that will catch any kind of text input.

Due to its special nature, explicitly do not give a guarantee for
compatibility; thus the warning in input.rst.
