Program caching makes whether or not this is safe a little subtle. It
is safe and I've tried to explain the subtlety in comments in the new
non-virtual Shader program() hook that forces all opaque shaders to
opaque, and in comments in SkVMBlitter where we make use of isOpaque().
I think this is the tidiest way to get the optimization and safety,
though it is a little awkward to have to write epic cross-referenced
comments explaining first why it might not generally be safe to use
shader->isOpaque() to make decisions in the blitter, and then how we
actually have made it really quite safe.
Many tiny partial-coverage diffs from how coverage interacts differently
with SrcOver and Src, SrcOver folding coverage into the src color before
blending with dst, Src just lerping with dst.
This all comes together really quite magically, changing a program to
draw a solid opaque color from this,

Now that we've turned paint colors into shaders where appropriate,
SkVMBlitter's Uniforms struct is only really holding one byte of
coverage for when we're in RLE coverage mode.
We can just pass that coverage as its own uniform pointer, much like we
pass a pointer for masks. This means there's no need to think about the
(notional) Uniforms struct any more, and leaves the first, main uniform
parameter holding shader uniforms exclusively.

I'd like to express each of the special automatic features of the color
pipeline as their own effects in SkVMBlitter where possible. This turns
the modulate-shader-by-paint-alpha feature into an explicit shader
wrapper.
This also sort of shows off how program() and uniforms() can chain
together. This is the same basic form that SkColorFilterShader will
take, since scaling by alpha is basically a color filter. (And indeed,
I may follow up by reformulating this as AlphaColorFilter once I get
color filters and SkColorFilterShader working with SkVMBlitter.)
Other next steps may involve factoring the pipeline's implicit
use-the-paint-color shader into an explicit shader.
Just FYI on the bug, thinking along its lines.

When rendering to a BottomUp render target, the SRIR-V codegen
needs a uniform to pass the render target height. (This is kind

the same hack that the Vulkan backend uses.)

It's not drawing anything earthshattering, but it does act as an easy
way to exercise some interesting code paths in SkVMBlitter, here first
program caching based on shader program and not shader identity.
With today's shader caching patches, this makes 2 calls to
skvm::Builder::done(), JITing the program, while if you patched this in
at head you'd see 3. I'd like it to get down to 1 by converting paint
colors to color shaders.

1) add a hash() method to skvm::Builder
This is cheap... we're hashing instructions as we go anyway.
Small refactoring to keep all its hashing close and clear.
2) split Key into Key (a small bytey hashy identifier)
and Params (a pointery typey payload struct)
3) dummy call ->program() on shaders as we build our Key,
and then include that dummy Builder's hash() in the key.
This lets us reuse cached programs when effects vary only in their
uniforms. The approach in 3) is meant to be a first draft, a kind of
can-we-get-away-with-this hack. We may need to change this with,
- stronger equality than just a hash of the instructions;
- a new cheaper hook that avoids the cost of skvm::Builder.

This adds `shader && paint alpha < 1.0f` to the blitter Key, so we'll
generate and cache two different programs based on that bit.
I put a little bit of effort into a different approach, wrapping the
shader with a new shader that modulates by paint alpha when paint alpha
is less than one. This should work, but I realized that it would break
caching, since we're caching based on shader identity. (Not really
break, but make it ineffective.)
I've added some notes about cache keys in general, and that this wrapper
approach would make caching less effective is I think enough to make me
want to work out a "identify yourself except for uniforms" protocol for
shaders (really effects, eventually color filters will need it too).

We'll lean on them being folded away before choosing blitters.
That happens everywhere but in Google3 now, and there's no use
of SkVMBlitter outside our own testing, certainly not Google3.

Change RemoteStrikes to hold a very small summary of what has been
sent for each glyph, and only maintain full glyph information
until the next serialization. This greatly reduces memory used,
and improves average performance by 10% as measured by traces from
the top 10 websites.

The conversion math for a given space can be fully derived
from the Kr and Kb terms (plus the headroom/footroom), so
avoid redundant values that can be wrong.
And, no need to list every possible value of an enum param,
especially when the generated doxygen links to the type's
documentation, which has all the values listed.

This should allow the bit field positions to be moved
around in the SkPackedGlyphID.
