QtWayland: Add support for TreeLandCaptureManager

The TreeLandCaptureManager is used to capture output contents or window
contents. It provides a way to capture frames from a source, such as an
output or a window, and then process the captured contents.

The TreeLandCaptureManager is designed to be used with the TreeLandCaptureContext,
which is responsible for managing the capture process. The TreeLandCaptureContext
can be created and destroyed, and it can capture frames from different sources
such as an output or a window.

The TreeLandCaptureFrame is responsible for capturing the frame from the source
and providing it to the client. It can also handle different formats of the
captured frame and can be used to copy the captured frame to a buffer.

The TreeLandCaptureManager provides a way to interact with the TreeLandCaptureContext,
allowing the client to select a source, capture a frame, and process the captured
frame.

The TreeLandCaptureManager and TreeLandCaptureContext protocols are designed to be
used with the TreeLandCapture protocol, which provides a way to capture output
contents or window contents.
