  Store shader interface variables as per query spec
  
  GLES 3.1 section 7.3.1.1 specifies how active variable entries should
  be generated and how active variables are named. The specs for program
  interface variable queries are built on top of this section.
  
  ANGLE has already followed this spec for the most part for generating
  variable lists in ProgramState, but now we also follow the naming spec
  for arrays and include [0] at the end of the stored name.
  
  This will make implementing arrays of arrays more straightforward.
  Most logic for variable queries will just keep working as is when
  arrays of arrays are added instead of needing more complex logic for
  handling array indexing.
