Update of the xdrgen tool.

I don't know what the merge criteria are for a tool like this, but
Jeff's delstid work depends on getting this merged first. I could
just pop it onto the nfsd-next stack, if folks think that's OK.

Changes include:
- Added some support for generating files for client side (not complete)
- Added a single SourceGenerator class, all others now inherit from that
- Split XDR pointers (optional data) into a separate class and generator
- Added Python type hints
- Lots of other minor cleanup
