Kevin Lubick 08ece0c9a0 [includes] Enforce IWYU on sksl code
PS1 regenerates the Bazel files. Use it as the base change when
    comparing patchsets.

IWYU seems to do a good job of working with MyFile.cpp and
MyFile.h, but if there is just a MyHeader.h, it doesn't always
seem to throw errors if the includes aren't correct. This was
observed with include/sksl/DSL.h This might be due to the fact
that headers are not compiled on their own, so they are never
sent directly to the IWYU binary.

This change sets enforce_iwyu_on_package() on the all sksl
packages and then fixes the includes until all those checks
are happy. There were a few files that needed fixes outside
of the sksl folder. Examples include:
 - src/gpu/effects/GrConvexPolyEffect.cpp
 - tests/SkSLDSLTest.cpp

To really enforce this, we need to add a CI/CQ job that runs
bazel build //example:hello_world_gl --config=clang \
  --sandbox_base=/dev/shm --features skia_enforce_iwyu

If that failed, a dev could make the changes described in
the logs and/or run the command locally to see those
prescribed fixes.

I had to add several entries to toolchain/IWYU_mapping.imp
in order to fix some private includes and other atypical
choices. I tried adding a rule there to allow inclusion of
SkTypes.h to make sure defines like SK_SUPPORT_GPU, but
could not get it to work for all cases, so I deferred to
using the IWYU pragma: keep (e.g. SkSLPipelineStageCodeGenerator.h)
