Give a user oriented label to the default custom properties in layer Information tab

[DelazJ]

What is the bug or the crash?

Layer properties --> Information tab has a custom properties section.
Some predefined custom properties seem to exist:

• dualview/previewExpressions
• embeddedWidgets/count
• variableNames
• variableValues

It could be nice to provide them with a more user readable name. this will be coherent with other default information in that tab: their label is clear and translatable.
And I would add to the list userNotes.

Moreover, one can guess what the last two are but I personally have no idea from where the first ones can be tweaked.

Steps to reproduce the issue

Open a layer properties and its Information tab.

Versions

Well, found out that embeddedWidgets/count refers at least to the widgets you can reuse in the Layer properties -> Legend tab.

I'm not sure if this is really a bug than rather an enhancement.

Anyway, if we do that (what means we do evaluate the content of the custom property keys: e.g. if variableName, then write "Variable Name" etc.), one might think about to make it smarter anyway, by e.g. representing the variableNames / variableValues not as single entries but combined in a table (or at least a map like "name":"value" etc.)...
