Raster labeling

PR Description:

Allows raster pixels to be labeled with the value taken from a raster band.

Labels are registered with the labeling engine, so participate in label conflict resolution and overlap avoidance

Options include

• Selection of band to take values from
• Using QgsNumericFormat to customise the number format for the labels
• Uses text renderer, so supports buffers, shadows, etc
• Label priority
• Scale dependant visibility
• Optional pixel size dependent visibilty, ie show only when pixels are > 4mm in size
• Z index control, overlap avoidance mode
• Option for showing values resampled over neighbouring pixels

Fixes qgis/QGIS#14408
