Jonas Ådahl 7c3172a0af kms/impl-simple: Add cursor plane processing
A cursor plane can now be assigned, and for the simple KMS
implementation, it'll translate into drmModeSetCursor() and
drmModeMoveCursor() calls.

When assignments failed, the cursor planes that failed to be assigned
are communicated via the feedback object.
