tdf#152104 speed xls->ods convert part 2 HEADmaster

We are doing a lot of work in ScAttrArray::SetPatternAreaImpl,
where we move the mvData vector of CellAttributeHolder around,
so inline and reduce some of the work.
The move operator= can be simplified, leaving some of the work
to the destructor (which may well be elided when moving
arrays of elements around).

Reduces time from 50s to 39s
