[Fix] (MG_State, MG_Backend/DirectGLES): preserve legacy texture reuse and clear default backend bindings - keep generated-but-unbound names alive for Minecraft 1.7.10 atlas uploads, synchronize bind-0 to native GLES without 1D/2D alias churn, and cover both paths with BGRA sub-image and binding-cache regressions
