Fix the addition of Kabyle language.

Data for this language was added manually in r75752, which meant that it was
going to be lost after the next regeneration of the automatically generated
files.

Add it properly, by updating misc/language/langtabl.txt now.

Handle wxLANGUAGE_CAMBODIAN correctly in the generation script.

Fix wxLANGUAGE_CAMBODIAN definition in autogenerated code, this was already
done manually in r76368 but these changes would have been lost after the next
generation, so update the script itself to generate them.

Closes #16183.

Add wxGraphicsRenderer::GetName() and GetVersion() methods.

Allow the code to determine which underlying technology is used for
implementing wxGraphics API. This is needed by the unit tests to account for
the known differences between platforms and may be useful in other cases.

Closes #16154.
