Kevin Lubick ee62fad9a4 [bazel] Add "skia_internal" target that exposes private API for tests/tools.
Organization v3.5, if we are keeping track :)

This splits the "srcs" filegroup into "srcs" and "private_hdrs",
and renames "hdrs" to "public_hdrs".

To assist with the split, I created the macro split_srcs_and_hdrs.
Rather than keep two separate lists of header and source files,
I figured it would be easiest, at least for the common case,
to keep one list of files and then have a for loop split them
apart. I've tried to be consistent with having the list
of files be named with a _FILES suffix - maybe we can use this
as a marker to generate .gni files in the future?

Suggested review order:
 - //bazel/macros.bzl. Note this needs a corresponding
   G3 change (http://cl/452279799) as well. The exports_files_legacy
   change is the better approach to something I manually
   handled yesterday when fixing the G3 roll.
 - //BUILD.bazel to see the new target skia_internal and
   the previous skia_core renamed to skia_public.
 - //src/core/BUILD.bazel to see a typical usage of
   split_srcs_and_hdrs.
 - //include/... to see the change to public_hdrs and
   private_hdrs
 - //src/... to see many more usages of split_srcs_and_hdrs
 - //tools/... to see changes to skia_internal where
   appropriate.
 - Everything else. Note that //modules/... might also need
   to be built with skia_internal instead of skia_public,
   but we can fix that up later, if necessary.

This allows us to experiment with making sk_app target the browser.

To build, make sure bazelisk is installed. (This is a wrapper around bazel). https://github.com/google/skia-buildbot/blob/main/BAZEL_CHEATSHEET.md#install-bazelisk

Then, run make debug to build the binary. To see the result on the web, run make serve and navigate to http://localhost:8000/hello_world.html

Presently, the //tools/sk_app/wasm/main_wasm.cpp only prints out hello world, but it should set up the surface/window for wasm and then call into the sk_app code.
