Check SAL_USE_COMMON_LAYOUT envar in one place
Makes it easier to flip the switch in the future (or even do something
more fancy other than checking envvar).

Re-enable Kashida insertion in CommonSalLayout
We now do Kashida insertion in ApplyDXArray(), no need for a separate
step. This simplifies the code greatly (old code is in
GenericSalLayout::KashidaJustify()).
