Simplify wxGrid::SetSelectionMode() selection updating logic

Browse Source 
Don't try to extend the existing selected blocks to rows/columns, this
contradicts the documented behaviour which is to discard the selected
blocks that become invalid in the new mode.

Do handle switching to wxGridSelectRowsOrColumns mode, as there doesn't
seem to be any reason not to.

Update the tests to check for the expected selection update behaviour.
