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).

Validate Kashida positions in CommonSalLayout
Currently checks only for ligatures, but that is a big improvement over
al code that didnât do any validation except on Windows.

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()).
