tdf#107348 tdf#45958 tdf#141215 tdf#141683 fix filtered/transpose paste

Row filtering, Special Paste transposing and multi range selections had
various issues. Since the same methods are used in different code paths,
I made a unified fix for these issues.
Moreover, Special Paste dialog allows the combination of options.
There are about 50 test cases for these various combinations of filtering,
selection, transposing and pasting options.

The following cases are supported and checked in test combinations:

* Transposing
* Filtering
* Multi range column and row selection
* All cell types: number, string, formula, rich text, empty
* Notes
* Formatting patterns (e.g. cell backgrounds and borders)
* Empty cell skipping
* Special Paste as link
* Merged cells
* Formula references:
* Relative and absolute references
* References to rows before and after filtered row
* References to filtered row
* Double references (e.g. A1:A3)

Notably the following cases are fixed and tested:

* Transposing of filtered data (tdf#107348)
* Copy/Paste of filtered multi range selections (tdf#45958)
* Transposing of filtered multi range selections (tdf#107348, tdf#45958)
* Notes at different position (tdf#141215 ^)
* Transposed multi range selection pasted as link (tdf#141683 ^)

^ = discovered during tests

Due to the unit tests, I refactored some code. Mainly, I extracted
methods to improve the readability and to avoid code duplication.
