Use long click timeout for handwriting

We've received several feedbacks that the current tapTimeout is too short,
making it very hard to initiate handwriting. To unblock us from bug bash,
this CL temporarily use long lick timeout for handwriting timeout.
Once UX decided the final value for handwriting timeout, we will create
another CL.
