Subject: [PATCH] Introduce vxworksevdev feature

VxWorks OS uses its own "compatible" implementation of evdev library,
but which doesn't have identical API and ABI. This makes maintaining
common code, which uses both evdevs, hard.

Add VxWorks-specific QT_FEATURE_vxworksevdev to detect VxWorks evdev
implementation. This is a preparatory change to introduce VxWorks-evdev
specific input plugins.

Task-number: QTBUG-115777
