Deprecate usage of Mir's input resampling, instead opting for:

Shell: Raw native input events Apps: Qt's built-in touch compression input resampling algorithm, and other toolkits are expected to provide their own. This fixes LP: #1497105 nicely, allowing apps to receive the full-speed input stream (if they ask their toolkit to give it to them). As an added bonus this also eliminates the 0-16.9ms (average 8.4ms) of input lag that apps under Unity8 would experience. We do still have the problem of output lag making everything still look laggy but I am working to eliminate that soon in Mir 0.26.0.
