HID: Add Tablet Pick -> BTN_STYLUS2 mapping
Many tablet input drivers use BTN_STYLUS2 code to report a second tablet stylus button. Yet, the generic HID input driver doesn't map it. Apparently, because there is no corresponding usage in the HID Usage Tables. This patch selects a compromise usage - "Tablet Pick" (0x46) to be mapped to BTN_STYLUS2. Some tablets use "Eraser" usage, but mapping it to a button wouldn't be entirely correct, because the specification says it may be "a pressure quantity".
