`writeStatement` has the potential to emit a trace_line op. In practice,
right now our function's outer Block never has a position, so there is
no difference. However, Ethan's position-related work will add a
position to this Block, which would expose this issue and break tests.

We already performed a matching simplification for `0 - x`, so this
seemed like a straightforward improvement.
Performing this simplification causes the expressions in the test code
to match on both sides (e.g. `-one == -one`) which allows them to fold
away.

These functions were functionally almost identical, except:
- Sometimes sda/dsa are flipped
- Sometimes the saturation is not updated
We now have one method (blend_hslc) which can do all four blend
operations. It takes two new parameters ("flip" and "saturate") to
handle these four variations.
This reduces our shader count on some of our most shader-heavy slides
(e.g. aaxfermodes, xfermodeimagefilter) at a pretty reasonable cost.

The internal ClipGeometry enum is moved to SimplifyResult in header.
The internal get_clip_geometry is renamed to Simplify and declared
header. This was so that the internal types (SaveRecord, Element, etc)
and TransformedShape could easily interoperate.
TransformedShape is a view that bundles references together instead
of requiring that all the internal types have some magical set of
functions that get_clip_geometry used.
The contains and intersect logic has all been consolidated into
TransformedShape instead of spread across many different contains()
functions. Intersect() is also more detailed because it can take
coordinate systems into account the coordinate systems, which will be
particularly useful when draw checking is added in a follow-up patch.
