mesa: actually check for EXT_color_buffer_float support

Browse Source 
EXT_color_buffer_float makes both 16 and 32 bit floating-point texture
formats color-renderable. We can't just unconditionally report that, we
need to check for support.

The RGB formats are a bit special under this extension, because it's not
specified as color-renderable. However, because the RGBA formats *are*
specified as color-renderable, and the state-tracker can emulate the RGB
formats with the RGBA ones, we don't need to test for that here.

While we're at it, move EXT_color_buffer_half_float to its correct
sorted position.
