Reorganized osd/patchBasis and osd/patchBasisTypes

Browse Source 
Folded osd/patchBasisCommon.h and osd/patchBasisCommonEval.h into the
single header file osd/patchBasis.h and renamed osd/PatchBasisCommonTypes.h
to osd/patchBasisTypes.h

Moved these into the OpenSubdiv::Osd namespace when compiled for C++ and
added a brief comment describing the intended use cases for this code.
