  Message : Add entry points for EGL_ANGLE_program_cache_control. This instruments the plumbing for the extension without adding any functionality or exposing the extensions string. The extension text is also updated to reflect the new entry point design and naming. Also this corrects a few mistakes. This will be followed up by the tests (which won't run) and then the extension functionality in ANGLE. BUG=angleproject:1897 Change-Id: I5b009e23bc27da06b067375525bd6fc574027702

      OpenGL ES Extension #??
  
  Dependencies
  
      OpenGL ES 3.0 is required.
  
      This extension is written against the wording of the OpenGL ES
      3.0 specification.
  
  Overview
  
      With the program cache enabled, created OpenGL ES contexts will use an
      internal program binary cache to save linking time. The extension allows the
      application to determine if a particular Context has this feature enabled.
  
  New Types
  
      None
  
  New Procedures and Functions
  
      None
  
  New Tokens
  
      Accepted by the <cap> parameter to IsEnabled and the <pname> parameter to
      GetBooleanv, GetIntegerv, GetFloatv, and GetInteger64v:
  
      PROGRAM_CACHE_ENABLED_ANGLE           0x93AC
  
  Additions to the OpenGL ES Specification:
  
      Add to section 2.12.3 (Program Objects), p. 52, after paragraph 4:
  
      Contexts with PROGRAM_CACHE_ENABLED_ANGLE set to TRUE will query the
      internal program cache on any LinkProgram call, and re-use program binaries
      if matching values are found. LinkProgram will succeed in this case. If the
      binary load fails for any reason, LinkProgram will fall back to linking
      normally.
