Support for automap options and resource binding shift (#2834)

Browse source 
* Support for automap options

- Added glslang_shader_options_t with enums for auto map bindings and
  auto map locations.
- Added options param to glslang_shader_parse.
- Modified glslang_shader_parse to call appropriate auto map function if
  auto map bits are set.

* Refactored auto map for C interface

- Added glslang_shader_set_options to independently set options instead
  of being a param on an existing function.
- Added glslang_program_map_io to call mapIO so auto map location
  actually works.

* Added support for shifting resource bindings

- Added resource binding shift functions to match C++ interface

* Uncommented preprocessor call that was commented out for debugging
