This emits SkSL that is more-or-less what the compiler re-ingests when a
runtime effect is used to create a GrFragmentProcessor.

The command-line length limit on Windows is very low (~8000 characters)
so it's infeasible to pass a large number of test files directly on the
command line. Fortunately, GN includes a built-in workaround.

skslc can now take a `.worklist` file as an input, containing multiple
"command lines" to run in sequence. compile_sksl_tests.py now assembles
a worklist file and runs skslc one time, rather than running skslc
once per each target. This improves compile times on Windows
significantly (where spawning skslc hundreds of times is much more
expensive than on Linux/Mac).
One subtle behavioral difference with .worklist files: if an error is
encountered, it is written to the output file instead of to stdout.
Previously, compile_sksl_tests was in charge of for capturing stdout
and overwriting the compiler output with the error message, but this
doesn't work when many files are being compiled (which errors are
associated with which files?)
This refactor exposed a minor latent bug--when encountering an error,
skslc would previously exit() immediately without closing its
FileOutputStream. This led to an assertion when exit() was replaced with
normal returns. Since FileOutputStream is only used by skslc, and in
every case the desired behavior is just to close the stream cleanly,
FileOutputStream now closes the file in its destructor instead of
asserting that we haven't done so.

We now support building an SkSL golden output twice, once honoring the
custom #pragma settings, and once more ignoring the settings. This
allows us to see the output of the workaround technique, alongside the
"default-settings" output which should not contain a workaround.
To implement this, skslc now supports a flag: --[no]settings.
When it's set, /*#pragma settings*/ comments are honored. When it's not
set, skslc ignores the comments. compile_sksl_tests.py passes this flag
along to skslc.
This approach is not strictly limited to workarounds; the
"TypePrecision" GLSL test was also updated to use this technique.

On Windows, the process output contains CRLF sequences. Calling
splitlines() recognizes those (Python universal line endings), so we get
a list of the output lines. Joining those with '\n' produces a string
that just has LF. (We add another one, so we still end the file with a
newline). Because we've opened the file in binary mode, the resulting
files now look the same, regardless of OS.

The new test files are intended to be identical to the unit tests in
every meaningful way. (Comments and formatting are not preserved
exactly.) In cases where a unit-test method contained more than one
test, multiple test files were created; in these cases, new names were
invented to match the apparent intent of each invocation.
Followup CLs will continue to migrate additional tests.

Golden SkSL outputs are intended to eventually replace the majority of
our unit tests, since they can automatically update themselves when we
change implementation details of the compiler.
If you change the compiler output without updating the Golden files, the
CheckGeneratedFiles housekeeper will be triggered. Set
`skia_compile_processors` or `skia_compile_sksl_tests` to true in your
GN args to regenerate them.
Almost all of the tests from SkSLFPTests.cpp and SkSLGLSLTests.cpp can
be migrated into separate unit-test .fp/.sksl files in a followup CL.
hcm@ has signed off on removing the copyright boilerplate preamble from
our unit test files.
