  Perf: Add _many_tex_draw test
  
  Add a new perf test _many_tex_draw, which draws with 8 textures bound.
  
  The intent of this test is to stress calls like retain() with various
  implementations of vk::Resource.
  
  Additionally, this CL updates the textures to use format GL_RGBA, rather
  than GL_RGB, to avoid the emulation step that's required due to the lack
  of support for the 3 channel format.
  
  Bug: angleproject:5971
  Test: DrawCallPerfBenchmark.Run/*_many_tex_draw
