Vulkan: Implement OES_get_program_binary extension 

- Serialize and deserialize completed shader source of
  program for saving out for glGetProgramBinary().
- Cleaned up some unnecessary includes in cpp files.
- Some refactoring within ProgramVk::ShaderInfo to minimize code
  duplication.
- Added ProgramVk::ShaderInfo::saveShaderSource and
  ProgramVk::ShaderInfo::loadShaderSource.
- Updated vk_caps_utils.cpp to enable getProgramBinary and add the
  GL_PROGRAM_BINARY_ANGLE program binary format. This follows the pattern
  for other backends.

Bug: angleproject:3216
Tests: dEQP-GLES3.functional.shader_api.program_binary*
