[Fix] (MG_Backend/DirectGLES): support Voxy rendering

Implemented:

- Advertise Voxy-required DirectGLES extensions without raising the reported OpenGL version.

- Add DirectGLES multi draw indirect count emulation and preserve GL draw indirect baseInstance semantics on GLES.

- Add DirectGLES DSA framebuffer clear/blit paths used by Minecraft and Voxy presentation.

Fixed:

- Rewrite gl_BaseInstance in DirectGLES vertex shaders and provide a backend uniform for indirect draw emulation.

- Materialize framebuffer attachment textures during DirectGLES FBO sync so named framebuffer operations do not desync backend attachment state.

- Avoid redundant texture buffer rebinding and handle texture buffers without bound storage during backend sync.

Tests:

- Add MG_Test coverage for DirectGLES Voxy extension advertising, baseInstance shader rewriting, and DSA named framebuffer clear/blit backend wiring.
