Kevin Lubick 4511c7b7fb [bazel] Delete gazelle-based BUILD.bazel files 
gazelle ended up being more liability than asset for our C++ rules.

It required devs to manually run the command frequently (and was
easy to forget until the CQ failed). The fact that we still had to
edit the source files (e.g. the "srcs" cc_libraries) meant that
the mixture between generated and hand-written caused some
tension (see include/third_party/vulkan for a good example).

The combination of gazelle and our IWYU enforcement added several
bits of churn without any real benefit. The generated rules
also didn't help identify cases where we were not keeping tight
boundaries (e.g. non-gpu code and gpu code).

Identifying third_party deps automatically ended up being trickier
than anticipated (see the deleted //third_party/file_map_for_bazel.json)

Using the "maximum set of dependencies" worked ok, but ended up
increasing build time unnecessarily. For example, compiling
CanvasKit for WebGL always needed to compile Dawn because
SkSLCompiler.cpp sometimes needs to include tint/tint.h.

Follow-up CLs will rebuild the BUILD.bazel rules without gazelle.

Note to Reviewers:
 - The only file worth manually reviewing here is bazel/Makefile.

Skottie iOS Example App

Metal

How to compile for the Metal backend:

cd $SKIA_ROOT_DIRECTORY

mkdir -p out/ios_arm64_mtl
cat > out/ios_arm64_mtl/args.gn <<EOM
target_os="ios"
target_cpu="arm64"
skia_use_metal=true
skia_use_expat=false
skia_enable_pdf=false
EOM

tools/git-sync-deps
bin/gn gen out/ios_arm64_mtl
ninja -C out/ios_arm64_mtl skottie_example

Then install the out/ios_arm64_mtl/skottie_example.app bundle.

CPU

How to compile for the CPU backend:

cd $SKIA_ROOT_DIRECTORY

mkdir -p out/ios_arm64_cpu
cat > out/ios_arm64_cpu/args.gn <<EOM
target_cpu="arm64"
target_os="ios"
skia_enable_gpu=false
skia_enable_pdf=false
skia_use_expat=false
EOM

tools/git-sync-deps
bin/gn gen out/ios_arm64_cpu
ninja -C out/ios_arm64_cpu skottie_example

Then install the out/ios_arm64_cpu/skottie_example.app bundle.

OpenGL
