With the CPU backend, there is no GrContext on the canvas, so we were
sending errors to the default handler (SkDebugf + assert), so editing
shaders was impossible. Now they fail gracefully (and produce a popup
window with the message).

Previously, all backends allowed the SkSL to be edited, and GL allowed
GLSL to be edited. Now any backend's source can be seen, and they can
all be edited (other than SPIR-V). Tested with HLSL and SPIRV. I don't
have a Mac available, but MSL should work, too.

In order to emulate OOP-R's behavior, GM needs to pass GPU-backed resources to a DDL recorder.
This change allows GMs to create GPU resources first (in onGpuSetup w/ a direct context) and then use them in onDraw (with only a GrRecordingContext).

For each skp in the corpus, we start a fresh instance of
Chromium (via puppeteer), draw the skp and measure that time.
This process is repeated a fixed amount of repetitions
and the median, the average, and the std deviation is reported
to perf (as well as the individual datapoints as an FYI).
Importantly (and something we'll need to change about
SkottieFrames), we measure the average time between frames
after unlocking the framerate. This ensures we account for
the time needed by the GPU to actually draw (flush() returns
after the GPU has all the instructions, but not necessarily
has been able to draw).
This implementation is very similar to the SkottieFrames
code; a notable deviation is the repetitions are handled
outside of the html, i.e. a new chrome window per run.
I explored using content_shell, but noticed that requires
building Chromium, which our infrastructure is not set up
to do well.

reading into an std::string relied on data(), which doesn't return a

Our "header" reading and writing code didn't agree, so we always failed
to recognize cached program binaries. The asserts in the testing sink
failed to notice, because we did get a 100% cache hit rate, but we
immediately discarded the data we received.
We now also check that we didn't insert anything into the cache, as a
proxy for doing any shader compile work. That change, plus the tweak to
set cached=false when the header fields are invalid (like we do if we
encounter problems further in the blob) detected the problem. Adding the
version tag to the start of the encoded blob fixes the test, and means
that program binary caching is actually working again.
This code still looks (and is) fragile. The next CL is going to rewrite
things to use SkReadBuffer and SkWriteBuffer, make the parsing code less
brittle, and give us a more robust way to detect failure anywhere in the
stream.

OOP-R, on the gpu thread, creates the DDL, pre-compiles its shaders, draws it, flushes and then deletes the DDL. This process triggered a bug (cf. https://skia-review.googlesource.com/c/skia/+/292818 and crbug.com/1056730).
Prior to this CL all the programs were compiled and only at the end was any work flushed - thus it was likely that the bound program would be reset to the correct value when rendering.
With this CL, the addition of the flush right before the DDL deletion, makes it more likely that the wrong program will be bound when rendering begins.

Parse embedded fonts into SkCustomTypefaces, and pass down the text
animation pipeline. Things seem to mostly work for Latin examples.
Most existing Lottie files come with embedded fonts (the option is
enabled by default), so to minimize disruption only use the new
feature as a fallback for typefaces which cannot be resolved otherwise.
Also introduce a builder flag to prioritize embedded fonts over native
(kPreferEmbeddedFonts), and plumb in existing tools for testing.
