3b39b7f5c6 Alias canComputeFastBounds to affectsTransparentBlack
This moves SkImageFilter's API closer to SkColorFilter's, and also
updates SkRecordDraw's PaintMayAffectTransparentBlack to be less
conservative.

Originally:
-canComputeFastBounds() handled aggregating behavior of the entire graph
  but it's a public API
-affectsTransparentBlack() was the private virtual for a specific node

Now:
-affectsTransparentBlack() handles aggregating behavior of the graph and
  is part of SkImageFilter_Base (mirroring SkColorFilter_Base).
-added onAffectsTransparentBlack() to clarify the per-node virtual that
  they can override.
-canComputeFastBounds() simply returns !affectsTransparentBlack().

There are some usages in our code that I kept using canComputeFastBounds
(e.g. SkPaint's computefastBounds) because it kept naming consistent.
In other places I updated to use affectsTransparentBlack since I thought
that made it clearer why we were checking that behavior.

`halfArray == floatArray` (when fAllowNarrowingConversions is on).

68587ae274 Add SkClipStack::replaceClip() separate from deprecated clip op
The replaceClip functionality was added to allow Android to move off of
generalized expanding clips. At the time, SkClipStack simply used the
kReplace_SkClipOp to handle it. In order to remove those expanding ops,
SkClipStack will need a proper implementation of replaceClip().

The clip elements have an additional field to mark if
it's a replace (and it's op will be kIntersect). Adds a temporary
getRegionOp() function to unify elements that use this field vs.
elements that use the deprecated clip op (i.e. if they were deserialized
from an SKP that recorded an expanding op).

Clients of SkClipOp that checked for replace ops use the new function
instead of referring to the enum value directly.

some test cases exercising expanding clip ops are deleted since they

d7437eec2e Fix for fuzzer-discovered error in SPIR-V with RTFlip.
SPIR-V code generation synthesizes some extra variables that don't
actually exist in the Program. Checking the ProgramUsage of these
variables would fail; ProgramUsage::get doesn't know about these
variables, so it asserts (and would consider them as dead even if it
didn't assert). We now track our SPIR-V bonus variables in a separate
set, and always report them as live.

4dca83162b Rename GrSurfaceDrawContext to skgpu::v1::SurfaceDrawContext
This CL is mostly mechanical. It:

replaces "src/gpu/GrSurfaceDrawContext.h" #includes with
         "src/gpu/v1/SurfaceDrawContext_v1.h" and reorders

replaces "class GrSurfaceDrawContext;" with
         "namespace skgpu { namespace v1 { class SurfaceDrawContext; }}"

replaces "GrSurfaceDrawContext*" with "auto" where possible
replaces "rtc" with "sdc"
replaces "surfaceDrawContext" with "sdc"
replaces GrSurfaceDrawContext with skgpu::v1::SurfaceDrawContext
reflows parameters as needed

This CL does not try to:

make skgpu::v1::SurfaceDrawContext V1-only
minimize the skgpu and/or skgpu::v1 prefixes

Those two tasks will be accomplished in follow up CLs. This CL is just trying to get the bulk of the mechanical changes comprehensibly landed.

a4953515af add array to the Uniforms
Note: I have changed from using a byte offset for index to
an ordinary array index at the builder interface, but the
builder converts this to a byte offset for the instruction.
This makes the API easier to use.

I've added pushArray, and pushArrayF to the Uniforms, and
convenience methods on the builder to take Uniforms.

I've expanded the tests to use the new API.

a2d22b2e08 Broke DSLVar into separate subclasses
Previously, DSLVar represented local, global, and parameter variables.
This splits it into three separate subclasses.

In addition to just being a cleaner API in general, this also addresses
an issue we ran into with the upcoming DSLParser: previously, a global
DSLVar's storage was not set correctly until DeclareGlobal was called,
so an AddToSymbolTable call prior to DeclareGlobal would create the
SkSL variable with the wrong storage, causing spurious errors on
global-only modifiers. But holding off on the AddToSymbolTable tends to
break constructs like "int x = 0, y = x", so improving the API seemed
like the best way to address it.

Now that we have greater type safety around variables, we can
potentially avoid having to call AddToSymbolTable for DSLVar and
DSLGlobalVar altogether, since we know they are both supposed to end up
in the symbol table, but that isn't something I want to change in this
CL.

The fuzzer quickly discovered that the newly introduced mat2-to-vec4
conversion code did not account for integer vectors. We now handle
`ivec4(mat2)` casts properly. This required some non-trivial
restructuring of the logic, but in the vast majority of cases, the types
will match and the end result will be identical.

25af480ad8 Remove GrBlendFragmentProcessor::Behavior::kComposeTwo.
Most uses can just use kComposeOne because the input colors to the
children are not used. However, SkShaders::Blend() cannot. Lift the
compose-two behavior to a new helper,
GrFragmentProcessor::MakeInputOpaqueAndPostApplyAlpha, and use that
in SkShaders::Blend().

d8d85b9b89 Reland "Don't key progams/pipelines on origin.""
Reland works around Adreno issue with this formulation of sk_Clockwise:
 (sk_RTFlip.y < 0.0 ? !gl_FrontFacing : gl_FrontFacing)

and instead adds this to the top of the function:
 bool sk_Clockwise = gl_FrontFacing;
 if (sk_RTFlip.y < 0.0) {
      sk_Clockwise = !sk_Clockwise;
 }

Original description:

SkSL language features that are origin sensitive now use a uniform
to conditionally flip their result rather than generating different
code.

Previously we would insert a "rt height" uniform if sk_FragCoord needed
to be flipped. sk_FragCoord,y was implemented as "realFragCoord.y" or
"rtHeight - realFragCoord.y" depending on SkSL::ProgramSettings::fFlipY.

Now we instead use a two component vector rtFlip and sk_FragCoord.y is
always "rtFlip.x + rtFlip.y*realFragCoord.y". We configure rtFlip as
either (0, 1) or (rtHeight, -1). sk_Clockwise and dFdy simiarly use
rtFlip.y to emit code that always works with either origin.
