  Vulkan: Support OES_shader_io_blocks
  
  Enables OES/EXT_shader_io_blocks extensions in Vulkan backends.
  
  With shader I/O blocks, the varyings can now be an array of struct (the
  block itself) of struct (nested in the block).
  
  This change is missing a number of features.  In particular, if the
  shader I/O block has a location decoration in the middle of the block,
  that is not handled yet.
  
  Based on changes from m.maiya@samsung.com and jmadill@chromium.org.
  
  Bug: angleproject:3580
  Tests: dEQP-GLES31.functional.shaders.linkage.es31.io_block.*
   dEQP-GLES31.functional.separate_shader.validation.es31.io_blocks.*
   dEQP-GLES31.functional.program_interface_query.program_input.*
