[Fix] (MG_Impl/GLImpl, MG_IntegrationTest, MG_IntegrationTest/Scenarios, MG_Remote/Client, MG_Test/Texture, scripts/data): make by-name texture calls act on the named texture

- The 19 calls that bound their texture first now share object cores with the target forms
- GL 4.6 rules the binding hid: cube maps in TextureSubImage3D and level queries, named target errors
