rsx: Do not rely on program env state, instead, always use program ucode analysis results when doing codegen

Browse Source 
- Some things can be present in program env but not ucode state
  e.g A texture can be active and bound in a redirected manner but not actually be used in ucode
  In such a case, only the ucode analysis or decompilation can decide whether to inject decoding routines
