canvas: rename snapshot(_data) to surface() -> SourceSurface/bytes() -> AsRef<[u8]> (#36793)

Browse source 
`surface()` returns `SourceSurface` which is/was meant as optimization
when passing from canvas to canvas (in vello that would be wgpu texture;
but raquote does not really have this) while bytes returns something
that must impl AsRef<[u8]> (this is more generic then `&[u8]` as it
allows us to have type with drop impl - wgpu's BufferView).

Testing: This is just refactoring (protected by rust), but there are WPT
tests.
