  Move set/get uniform machinery to ProgramExecutable
  
  This is done because some uniforms are internally added by the compiler
  (draw ID, base vertex, and base instance) and are automatically set **on
  the installed executable**.
  
  This change fixes scenarios where a draw is done after a program has
  failed a relink, and therefore is unable to correctly set the uniforms
  (as it does not have access to the executable that is installed).
  
  It also fixes draws that use those uniforms in a PPO.
