CRTP base for compact unwind traits classes.

Automatically provides derived constants.

FIXME: Passing PtrSize as a template parameter is a hack to work around a bug in older MSVC compilers (until at least MSVC 15) where constexpr fields in the CRTP impl class were not visible to the base class. Once we no longer need to support these compilers the PtrSize template argument should be removed and PointerSize should be defined as a member in the CRTP Impl classes.
