Graphite code snippets can be moved into these files; they will be
compiled once at build time and dehydrated for later use. This allows us
to avoid synthesizing and compiling them in each shader where they are
referenced. (Unfortunately, the GPU driver will still need to compile
them each time.)

For now, the hierarchy of module dependencies is hard-coded into
dehydrate_sksl.py. (It is already hardcoded into SkSLCompiler.cpp, but
not in a way that is easily accessible to sksl-precompile.)
sksl-precompile now takes one output and an arbitrary number of inputs.
The inputs are processed from right to left, layering their symbol
tables as we go. e.g., sksl_frag is compiled like this:
sksl-precompile sksl_frag.dehydrated.sksl sksl_frag.sksl sksl_gpu.sksl
At present this doesn't change anything, because every module is
written in a standalone fashion (since nothing else was allowed). I've
demonstrated that these changes actually work as intended in a
followup example CL (not meant to be submitted).

gn flag `skia_compile_modules` now compiles the `sksl-precompile` binary
and generates dehydrated data. gn flag `skia_compile_sksl_tests`
now compiles `skslc` and builds the SkSL test corpus, but does not
generate dehydrated data. (skslc uses the raw sksl_xxxxx.sksl inputs
directly, not the dehydrated data, so this is safe.)

Probably ok to just make it do what normal build
steps do, only print anything with ninja -v or

Explanation: The sksl standalone compiler is used to convert the raw
(text) SkSL pre-includes into a "dehydrated" binary format. It also
(previously) depended on those files, as they were #included and used,
unless a special #define was changed. This created a dependency cycle
that we hid from GN (by lying about the outputs of the dehydrate step).
As a result, builds would never reach steady-state, because the compiler
would be rebuilt (due to the newer dehydrated files), and then the
dehydrated files would be rebuilt (due to the newer compiler).
This CL changes the logic so that the standalone compiler always uses
the textual pre-includes, and no longer depends on the dehydrated binary
files. Thus, to make any kind of change to the dehydrated files (whether
due to pre-include changes, or the encoding format itself), you just
need skia_compile_processors enabled. The dependencies are now honestly
communicated to GN, and we reach steady state after one build.
The NOTE above is because GN/ninja cache the dependencies of each
target, and will still think that the SkSLCompiler.obj linked into the
standalone compiler depends on the dehydrated files, at least until one
successful build, when it will realize that's no longer true.
Reland notes:
The bots originally rejected this CL, because SkSLCompiler was
hard-coded to load the text files from a relative path that assumed the
executable was in "<skia_checkout>/out/<some_dir>". That's not true for
bots, and it was fragile, even for users. Now, we use GN to directly
generate sksl_fp.sksl, and copy all of the other pre-includes to the
root out dir (working directory when running skslc). This means we
no longer need to generate the sksl_fp.sksl file into the src tree, and
the compiler can more safely assume that the files will be in the
working directory.
