svga: add format conversion for legacy formats

This patch extends the format_conversion table to support
different view formats on texture buffer.
For legacy image formats such as INTENSITY, LUMINANCE, LUMINANCE_ALPHA,
special swizzle masks will be used on the red or RG channels.

This fixes piglit test arb_texture_buffer_object-formats fs|vs arb
