Multi-screen handling for the eglfs_kms_egldevice backend

Separates the generic kms classes into a own kms static lib
called QtEglFsKmsSupport. The eglfs_kms plugin was changed
to use these base classes and got renamed accordingly to
QEglFSKmsGbm*.

The eglfs_kms_egldevice plugin got extended to also derive
from the kms base classed and by this provides multi-screen
support
