Subject: [PATCH] mesa/es: Validate glGenerateMipmap target in Mesa code rather
 than the ES wrapper

v2: Add proper core-profile and GLES3 filtering.

v3: Fix a typo in GL_TEXTURE_2D_ARRAY checking.

v4: Change !_mesa_is_desktop_gl tests to _mesa_is_gles test.  The test
around GL_TEXTURE_2D_ARRAY got some other changes because that enum is
also available with GLES3 (which uses API_OPENGLES2).  Based on review
feedback from Eric Anholt.
