tdf#124944 don't directly adjust fallback layouts

These are adjusted via MultiSalLayout::AdjustLayout, as they
just know their own text width, but not the full text width of
the MultiSalLayout, so the adjustment is too large.

The correct adjustment is done by preparing a DXArray for all
glyphs, which is then passed to the individual font fallback
layouts for general adjustment.
