platform/x86: asus-wmi: map more keys on ExpertBook B9

* there is a dedicated "noise cancel" key in top row, between mic mute
  and PrintScreen; it sends 0xCA when pressed by itself (mapped to F13),
  0xCB with Fn (mapped to F14)
* Fn+f sends 0x9D; it is not documented in the manual, but some web
  search results mention "asus intelligent performance"; mapped to FN_F
