If we start with an OpConstantComposite, then we do an
OpCompositeExtract from it, we can look up the result directly from op
cache and avoid doing any work. This helps our matrix code a lot.

Many chromium adjacent projects have started using this repo to fetch
all of the Vulkan and SPIRV repos in a single bundle. Using this ensures
that we get a group of repos that should work together (atomically), and
simplifies autoroller configuration (we just need one roller for
vulkan-deps that does transitive rolls of the children, rather than five
separate rollers).

PaintRotate needs to rotate counter-clockwise, but was rotating
clockwise due to passing the font's value unchanged to
SkMatrix::RotateDeg. Negate the value to achieve counter-clockwise
rotation.
For PaintSkew, we compute the tangent from the values in the font and
set up a skew matrix with that. Since we're using the trigonometric
functions to set up the matrix, the angle works in counter-clockwise
direction.
So this previously worked correctly for skew in the x
direction, but not in the y-direction due Skia using a y-down coordinate
system. Negate the y-angle from PaintSkew before calculating the
tangent and setting up the matrix.

The real std::span::subspan in C++20 allows the "count" argument to
default to `std::dynamic_extent` (a fancy way of spelling ~0U). I didn't
think it would be worth adding `skstd::dynamic_extent`, but I did have
a use for an unbounded subspan, so I added a single-argument version to
SkSpan.

The field SkGlyph::fForceBW is currently used by the DirectWrite
SkScalerContext implementation to let generateImage know that
generateMetrics needed to fall back to aliased rendering in order to
load the glyph. This is part of a more general issue where
generateMetrics must generate the metrics based on some glyph
representation and then generateImage must use that same representation
to draw.
Currently this consistency comes from ensuring that generateMetrics and
generateImage make the same decisions, with the only real information
passed from generateMetrics to generateImage being the mask format.
However, there have always been multiple glyph represenations for a
given mask format (like outline masks vs. embedded bitmap masks) and now
there are four (soon to be five) different color formats. While the mask
format and bounds are enough to allocate the space for a glyph
rendering, this is not enough information for generateMetrics and
generateImage to agree on which glyph rendering to choose. The
additional required information has come from implicitly coding
generateImage to make the same decisions generateMetrics would have.
However, these decisions may have been based on information which is
expensive to compute, like probing the font for which representations a
glyph may have.
To transmit this extra information, formalize that generateMetrics may
state which decisions it made (which glyph representation it used) so
that generateImage can use this information explicitly instead of
implicitly. Do this by expanding fForceBW and renaming it
fScalerContextBits and documenting what it is used for.

We have a new `writeInstruction` call which can cache instructions as
they are written. This allows us to reuse existing instructions instead
of recomputing the same things twice.
This feature is largely untapped in this CL. As a demonstration that it
works, we no longer check the `fNumberConstants` map when writing
numbers, and instead rely on the cache to deduplicate OpConstant
instructions. Followup CLs will leverage the feature more heavily.

SkVMDebugTracePlayer unless the appropriate GN or Bazel flag
is set (skia_enable_sksl_tracing and enable_sksl_tracing,
respectively). There was an existing #define that CanvasKit
used (CK_INCLUDE_SKSL_TRACE) and this was changed to
SKSL_ENABLE_TRACING.
Users of //:skia_core no longer need to specify a JSON dep,
