Synaptics refactor

[1Revenger1]

This PR brings some significant changes to both querying the trackpad at startup and handling packets. The querying makes it clearer what feature bits are being looked for, and to use them in the driver itself (for example setting the mode bytes). This also relies on my VoodooInput PR (acidanthera/VoodooInput#22) for fixing some trackpoint bugs as well.

Bugs this should fix:

• Rapidly opening pages in browsers while scrolling with the trackpoint
• Buttons on various trackpads (especially those without trackpoints attached) (VoodooPS2 clickpad buttons not working.  bugtracker#1579)
• I'm hoping this fixes DynamicEWMode problem on Lenovo ThinkPad Laptops bugtracker#890 as well. This checks a few extra bits to see if the trackpad supports Extended W.

Notes:

• This always puts the trackpad into Extended W mode if the trackpad supports Extended W.
• I left the old VoodooInput API in there for trackpoints to keep compatibility with other drivers, though it may be worth moving the Elans driver over to the new message/report struct.
• The VoodooInput changes change the multiplier to be a fraction over 64 to allow multipliers below 1, though I'm not sure how needed this is. I'm open to reverting this change if people don't see a need for this since it's not really an intuitive change. A multiplier value of 128 would effectively be a 2x multiplication with this change.

This fixes the trackpad on my MSI GP62 6QF running Ventura, thanks!

@1Revenger1, I merged the other commit, but at least static analysis is broken.

Seems that nothing got broken on ProBook 4520s with High Sierra
