Excel: for selection covering more than one cell, announce the active cell when pressing Enter or Tab rather than the whole selection range

[CyrilleB79]

Link to issue number:

Closes #6959

Summary of the issue:

When multiple cells are selected, pressing commands that move the active cell (even in a selection) do not allow to report which cell is active in the selection. We should more clearly distinguish between the selection and the active cell in Excel.

This had already been done for Libre Office in #12849.
