Provide style categories for raster layers

PR Description:

On copy/paste

Until now one only could copy/paste all categories (AllStyleCategories) on raster layer, what meant the following categories where considered:

• LayerConfiguration
• Temporal
• Elevation
• MapTips
• Notes (what means right click -> layer notes)
• CustomProperties
• Symbology
• Rendering (including Histogram stuff)

New you can choose what categories you want to consider.

Additionally AttributeTable is available to store the path to FileBasedAttributeTables.

Note: Symbology and Render are are melted together in the pipe object, they cannot be split. Means when Symbology is chosen as well Render parts are exported/imported and when Render is chosen as well Symbology parts are exported/imported - maybe one could split, but it would lead to backwards incompatibility.

On save/load to file

Until now only those categories could be stored and loaded with QML/SLD file:

• Symbology
• Rendering
• CustomProperties

by selecting Symbology category only.

Now here the categories mentioned above are provided as well.

Note Not implemented are:

• Categories Symbology3D, Labeling, Fields, Forms, Actions, Diagrams, GeometryOptions since they do not make sense for rasters
• Legend Category - because it has no effects yet. The Embedded Widgets are concerned by the CustomProperties and the Legend placeholder image is not yet handled at all (neither in the vector layers).
• Section QGIS Server is not yet handled at all (neither in the vector layers).
• Section Metadata is provided by QMD export separate

Additionally I removed the reading of customProperties in every case 613e83b2611191017f766b3304b8073ef5057016 since it was read double.
