e94b52c442 [canvaskit] Add skottie to Bazel build
PS 1 regenerates existing Bazel files
PS 2 adds generated Bazel files to skottie and its dependencies,
as well as incorporating it into CanvasKit.

This changes the version of Bazel we use to 5.0.0 (recently
released).We had been using a pre-release of 6.0 because we
wanted the new features in one of the 5.0 release candidates,
but not the regression that was there (and reverted before the
full 5.0 release). I'd like to stick to the latest stable Bazel
release where possible.

Suggested Review Order:
 - //modules/skottie/BUILD.bazel (this was hand written
   to encapsulate the skottie library). The files in the
   deps are based on skottie.gni.
 - //modules/skresources/BUILD.bazel and //modules/sksg/BUILD.bazel
   which expose all sources
 - //third_party/file_map_for_bazel.json which ignores the
   ffmpeg libraries (we won't actually build the SkVideoDecoder
   stuff because HAVE_VIDEO_DECODER is not set).
 - //modules/canvaskit/BUILD.bazel which makes use of the skottie
   library and includes the interface skottie.js file.
 - .bazelversion which changes the Bazel version used (e.g. by
   Bazelisk).
 - All other changes should be auto-generated or related to
   deleted files.

8ed49ea6e3 [infra] Add Bazel rules for codecs.
This ports the third_party BUILD.gn files related to codecs
(with a best-effort on arm/SIMD stuff). This includes:
 - libpng
 - libjpeg-turbo
 - libwebp
 - wuffs (gif)
 - libgifcodec
 - dng_sdk and piex (raw codec)

This expands the string_flag_with_values macro to allow
multiple values to be set at once. This was added in Bazel 5.0.0,
however the latest pre-release version of that has a bug [1]
which slows down compilation dramatically. This was fixed at
ToT, but not released. As a result, I started using the Bazel
6 pre-release (via bazelisk).

The macro select_multi makes writing select() where multiple
elements could be on possible/easier.

One can try compiling certain codecs by running:
bazel build :skia-core --config clang --include_codec=raw_codec --include_codec=png_codec

Suggested Review Order:
 - bazel/macros.bzl
 - bazel/common_config_settings/defs.bzl and its BUILD.bazel
   to see how the codec options are defined.
 - BUILD.bazel to see how the codec settings are used.
 - src/codec/BUILD.bazel to see the inclusion of Skia files to
   deal with specific codecs.
 - third_party/BUILD.bazel (while referencing the corresponding
   BUILD.gn files, such as third_party/libwebp/BUILD.gn)
 - Everything else.
