Ensure that such use cases as forced-csd environments don't cause the desktop window to be decorated

As the UI doesn't have semantic groups for owner/group/others settings
but they are only visually apparent, add some more context to the
accessible version of the labels to identify what it targets.

This is especially useful for the setting for other's permissions,
because the focus never lands on the line with the "Others" label,
hence making it hard to infer the context while navigating.

Another solution would be to redesign the UI to have semantic groups,
like e.g. labeled frames, but it's a lot less trivial and a lot more
intrusive a change.

Neither the button nor the icon shown in the properties dialog had nay
name, which is a problem for accessibility as an assistive technology
thus doesn't have anything to present to the user apart from an unnamed
button or image -- which isn't particularly helpful.

Improve this in two ways:
* Add a description to the icon, either matching the file type display
  name of the icon, the fact it's a custom icon or conveying multiple
  files are selected and the icon is hence not very specific.
* Add a tooltip to the button hinting that it can be used to change
  the associated icon.

Create a custom macro akin to G_DEFINE_TYPE() in order to generate the
boilerplate.
