Disable deep press when long press timeout is long

If the user sets the long press timeout to anything > default value,
then we should disable deep press. That means, if the user is triggering
long press too easily, it is likely that the user will trigger deep
press too easily as well.
To prevent unwanted long press invocations, we disable deep press in
such situations.

Bug: 148311342
Test: Add logging to both cases where deep press is enabled and
disabled. Go to accessibility -> touch & hold delay, and change the
value. Ensure that the logging matches expectation (short -> enable,
medium/long -> disable). The state should persist across the reboot.
