This implementation leans heavily into DSL. I also reworked the
`normalize` intrinsic to use more DSL to shrink the implementation.

This one is structured a bit differently; it gets to length() value,
then divides the input by its length using a bit of DSL. Since all the
inputs are constant, the constant-folder will do the right thing.

Every stroke shader just has conic branches now. The conic/cubic math
is mostly unified anyway, so a couple small branches shouldn't affect
perf.

Now that hardware tessellators chop, support raw triangles, and can
handle any path, we don't need complicated logic anymore to determine
when we can't use them. This CL simplifies the criteria for selecting
a tessellation algorithm and adds a fAlwaysPreferHardwareTessellation
context option to override it.

If every use of the coords passed to main was for a call to sample that
was converted to pass-through sampling... We don't actually reference
the sample coords, so we can un-set the flag. This prevents the FP from
requesting an extra set of (unused) coords, which saves a varying
between the vertex and fragment shaders.

As explained in the bug and comment - if the only reference to sample
coords is from a sample call that gets converted to pass-through, we
don't *actually* need the coords. We don't realize that with today's
analysis, so we end up generating a set of coords for the FP, which is
wasteful (adds an extra varying).

Previously, `evaluate_intrinsic_1_of_type` and related functions were
all templated on the lambda expression of each evaluation function, so
every intrinsic generated a copy of each function. In most cases this
could be replaced by a std::function which takes and returns a float,
bool or SKSL_INT. (This level of flexibility was only truly necessary
for `evaluate_intrinsic_numeric1`.)
