Fix issues from mixing regular/MSRTT multisampled renderbuffers Mixing resolved and unresolved attachments results in inconsistent sample states within the FBO, which violates the completeness requirements. In ANGLE, the framebuffer completeness logic checks RenderToTextureSamples only if the first attachment uses MSRTT mode. However, it fails to account for cases where the first attachment uses regular (non-MSRTT) mode. As a result, when the same framebuffer is later used with MultisampledRenderToTexture, the sample count mismatch between attachments may go undetected or misinterpreted, leading to incorrect completeness status.
