Now that no one is using the linear metrics flag directly, change the
meaning from 'no-hinting and subpixel positioning at an odd size when
measuring and just no-hinting when drawing' to meaning 'use linear
metrics'.
This also changes the font hosts to no longer use subpixel positioning
as a proxy for this value. This fixes outstanding bugs in Chromium about
getting the right metrics for hinted fonts.

Similar to the Skottie refactor that just landed, this avoids having an
empty component when shaper is disabled (which turns into a DLL with no
sources, and a missing DllMain). I think this pattern of having modules
expose the same components as empty groups is simpler (and also fixes
the fact that only two of N references in top-level BUILD.gn were
guarded). Also, no one is using the define?

Skottie doesn't currently build with is_component_build=true. Trying to
build a DLL with skia_enable_skottie=false failed, because we ended up
with a component("skottie") that had no sources. That led to fallback
linker behavior, but no DllMain.
To solve this, and simplify things, move the skia_enable_skottie checks
to the outer scope, and simply replace all the referenced components
with empty groups when it's not enabled. Also fix some fm code that was
assuming it was always enabled.

To avoid that, we can

2) clamp the image size to something reasonable (2K^2)

Two issues:
1) Empirically (per AE's model), only solid layers transform the effect space.
All other layer types implement their effects ignoring the layer xform.
2) Due to the effect deferral mechanism in sksg, shader effects are
sometimes applied with a different transform than intended.
To address #1, tweak the layer builder logic to attach the effects
before/after the transform node, depending on the layer type.
For #2, track the CTM active when the shader effect is attached and undo
any intervening transformations via a local matrix when the shader is
actually applied to SkPaint.

Refactor SkottieShaper to handle vertical adjustments based on a VAlign
enum:
kTop - the topmost line is ascent-aligned with the box top
(AE text-box behavior)
kTopBaseline - the topmost line is baseline-aligned with the top box
(AE text-point behavior)
kCenter - the text center is aligned with the box center
("sk_vj": 1, Skottie extension)
Also externalize the vertical adjustment as a text blob offset (instead
of baking into blob glyph offsets).

* refactor gradients as Shader subclasses
* introduce ShaderPaint (to support current Gradient-as-paint use)
* introduce ShaderEffect (to support future Gradient-as-effect use)
Tangentially:
* rename SkSGPaintNode.h -> SkSGPaint.h
