This pull request adds support for the standard VertexAttribDivisor in the GLES backend of Impeller, falling back to VertexAttribDivisorEXT if the standard version is unavailable. It also ensures VertexAttribDivisorEXT is reset if the GL_EXT_instanced_arrays extension is not present, and includes corresponding unit tests to verify this behavior. There are no review comments, and I have no additional feedback to provide.

In const bool hardware_instanced = instanced && //
gl.DrawArraysInstancedEXT.IsAvailable() &&
gl.DrawElementsInstancedEXT.IsAvailable() &&
gl.VertexAttribDivisorEXT.IsAvailable();... and would need to incorporate Also, should we be giving this same treatment to |

Yes - Updated this to check for the |
…orEXT on GLES2 with the extension OpenGL ES 3.0 includes support for glVertexAttribDivisor. The glVertexAttribDivisorEXT API is available on OpenGL ES 2.0 devices with the GL_EXT_instanced_arrays extension. GLES3 devices may be able to resolve a glVertexAttribDivisorEXT function that is not actually implemented. This PR uses the glVertexAttribDivisor API if available and otherwise falls back to glVertexAttribDivisorEXT. See flutter#186653
