GLES1: GL_OES_draw_texture BUG=angleproject:2306 This implements GL_OES_draw_texture using a few bits of new state in the renderer and adding a code path for it in the shader, using gl_VertexID to draw the quad backing the texture draw. This allows us to avoid allocating a separate vertex array for the texture draw and reuses the current shader as much as possible, plugging in to the existing multitexturing pipeline. - Add unit test and sample - No new test expectations, but advertising GL_OES_draw_texture makes the DrawTex GLES1 conformance test non-trivial and actually test glDrawTex*.
