Input: Add isStylusToolType() utility function
Using this utility function will ensure we don't forget to check for
both TOOL_TYPE_STYLUS and TOOL_TYPE_ERASER when we are looking to
identify a stylus.
This will cause a behavior change in UnwantedInteractionBlocker, where
TOOL_TYPE_ERASER was not previously considered a stylus tool.
