If we make sure all SkOpts functions are static, we can give the namespaces any
name we like. This lets us drop the sk_ prefix and give a real indication of
the default SIMD instruction set rather than just saying sk_default.
Both of these changes help debugger, profiler, and crash report readability.
Perhaps more importantly, keeping these functions static helps prevent
accidentally linking in unused versions of functions, as you see here with
sk_avx::srcover_srgb_srgb().
This requires we update SkBlend_opts tests and benches to call SkOpts functions
through SkOpts rather than declaring the methods externally. In practice this
drops testing of the SSE2 version on machines with SSE4. If we still really
need to test/bench the compile time best SIMD level version of this method
against the runtime detected best, we can include SkBlend_opts.h into the tests
or benches directly, similar to what we do for the trivial, brute-force, or best
non-SIMD versions.

This means we can remove a lot of explicit casts in code that uses SkNx.

- one base case and one N=1 case instead of two each (or three with doubles)
- use SkNx_cast instead of FromBytes/toBytes
- 4-at-a-time Sk4f::ToBytes becomes a special standalone Sk4f_ToBytes
If I did everything right, this'll be perf- and pixel- neutral.

This allows us to express shuffles more directly in code while also giving us a
convenient point to platform-specify particular shuffles for particular types.
No specializations yet. Everyone just uses the (pretty good) default option.

(Sk4f(float) is statically initializable, unlike the old SkPMFlor(SkPMColor).)

This lets us avoid conversions to [0.0, 1.0] space and rounding that aren't necessary
for SkColorCubeFilter_opts.h.
Dropping rounding on the way back to bytes means we'll see a bunch of off-by-1 diffs.
Rough perf effect:
SSSE3: 110 -> 93 (~15%)
NEON: 465 -> 375 (~20%)
This is the beginning of the end for SkPMFloat as an entity distinct from Sk4f.
I've kept it for now so I can convert sites one by one and think about how things
that really want to keep PM color order will work.

SkPMFloat(0) and SkPMFloat(0,0,0,0) end up with the same value,
but the first goes through math to get there. The second is a lot more
transparent to the compiler, and should compile all the way down to
just `xorps xmmN,xmmN` or even be optimized away.
Didn't measure any additional benefit from hoisting the zero outside
the loop and writing `SkPMFloat color = zero;`.
Perf win is <2%.

This is about a 12% improvement on my desktop, from 134 to 118ms on our bench.
