Fix windows build after gui regeneration

- vulkan/nolink is not a valid target, instead pass along vulkan
  include directories to consuming targets, and don't link to the
  library at all
- fix vulkan support target name in the windows qpa dependencies
- the wrong opengl dynamic feature was used in the windows qpa
  (the current way is consistent with qmake, otherwise
  there were issues with the feature evaluation, because
  gui feature definitions are not available in the qpa
  project scope)
- fix issue with qfloat16_f16c not being built because
  of previous subarch issues
