svga: return 1 for PIPE_CAP_MIXED_COLORBUFFER_FORMATS

This is actually required for GL_ARB_framebuffer_object, but the state
tracker doesn't currently check it.
Direct3D 9 allows mixed format color buffers with some restrictions.
Setting this allows Unigine Heaven 2.5 and 3.0 to run.  Tested both on
GL and D3D hosts.
