* It's already optional on linux due to distributions not necessarily
carrying packages for it yet. We also make it optional on windows
since by the same measure it's not a huge problem if it's missing, and
official builds will include it. This means we don't have to ship the
binary dependencies
* The main addition here apart from some extra stubs is a new rdc type
for date time objects.
* Although the module doesn't do anything and is only used for docs
reflection it is desirable to not have to link against Qt as this
can cause problems when linking the module without unresolved symbols.
* These .py wrappers are relevant for the non-builtin path, but since we
use -builtin they serve no purpose except to make things more complex.
* So instead we make the module directly exported as 'module' instead of
'_module'.
* On windows there's no conflict because we have renderdoc.dll vs
renderdoc.pyd. On linux it's librenderdoc.so vs renderdoc.so.
* To prevent supporting files like .lib / .pdb from conflicting on
windows we build the python modules into a subdirectory. They're not
ever used by the UI (it links in the bindings directly).
