Replace nodrop -> notallow to unify cursor themes

[Pilot-Pirx]

X11 cursors are the only that use "nodrop" instead of "notallow" cursor.

@ardovm Can we get rid of the redundant X11 cursors in
https://github.com/apache/openoffice/tree/trunk/main/vcl/unx/generic/dtrans
?

Maybe we can add a path to "unx/x11_cursors" here?
https://github.com/apache/openoffice/blob/trunk/main/vcl/unx/generic/dtrans/X11_selection.cxx#L54

Could you please elaborate a bit about this PR? How can we display the cursors you are working on?

[Pilot-Pirx]

I can display and open them with GIMP by renaming from .h to .xbm.

The 4 cursors are identical to those in:

[ardovm]

Thanks, where are these cursors used in the OpenOffice interface?

[Pilot-Pirx]

They are for Drag and Drop operations.
I usually test them in Writer by dragging content in a table from one cell to another.

I tried exactly that, and it seems to work!
