pass over the make RDI library

- Handle type layout in the library so converts simply
  define type graph and let the library handle DAG layout.
- Changed location baking. For now the library waits for scope, procs,
  global vars, and thread vars steps to serially finish because
  of common dependency on location sections, we need to parallel for each step.
- Changed encoded offset size for RDI_EvalOp_FrameOff to 8 bytes
  (1 byte is not enough to cover all cases)
- Added frame base location to RDI_Procedure (WASM encodes frame base
  as an index into a global array and so we have to resolve the base
  at runtime).
