Order of Surface TextureFormats has changed

[sotrh]

Description
The order of surface TextureFormats has changed unexpectedly. It orginally specified srgb TextureFormats before linear ones, but in the update to 0.15 the order changed to specify linear formats before srgb ones. Many users expect the first format in the list to be an srgb format and upgrading to 0.15 causes the rendering to be darker than expected.

Repro steps

• Take this code and run it.
• Update wgpu to 0.15

Expected vs observed behavior
Expected: The rendering should stay the same, or at least the change should be noted in the 0.15 change log.
Observed: the rendering is darker than expected.
