Refactor QNX camera support

Introduce a brand new QQnxCamera class that models around the QNX camera
API, and represents an underlying camera unit. As a result, QQnxCamera
is a self-contained and orthogonal class that no longer inherits from
QPlatformCamera.

A new class called QQnxPlatformCamera has been introduced to provide the
QPlatformCamera implementation for QNX.

While QQnxCamera remains close to the underlying QNX camera API
(including the types being used), QQnxPlatformCamera sits one level up
and makes use of a QQnxCamera object to expose it to the Qt-compliant
API/types.

QQnxCamera also enabled doing without the code duplication in
QQnxVideoDevices, vastly simplified that class.
