HLSL: Member-functions: capture body token stream for deferred syntax/semantics.

Browse source 
This is needed for accessing types/variables within a member function body that are
not known until after the struct is finished being declared. However, that funtionality
is not yet present, this is just the deferred processing, which is working for
static member functions.
