Since bbefc05748, both serialization formats in the VM are based on clustering. The distinguishing feature of the older clustered serializer is that it represents apps/programs rather than messages.

Note: This is a reland of https://dart-review.googlesource.com/c/sdk/+/150343
Adds a new SDK hash to kernels and the VM which is optionally checked
to verify kernels are built for the same SDK as the VM.
This helps catch incompatibilities that are currently causing
subtle bugs and (not so subtle) crashes.
The SDK hash is encoded in kernels as a new field in components.
The hash is derived from the 10 byte git short hash.
This new check can be disabled via:
tools/gn.py ... --no-verify-sdk-hash
This CL bumps the min. (and max.) supported kernel format version,
making the VM backwards incompatible from this point back.
This also bumps the min. and current ABI version.

Dev and beta version strings will look very look very similar, so adding
the channel name will make it easy for users to see if they are on be,
dev, beta, or stable. This will change both the output of
`dart --version` as well as the value of `Platform.version`.
This also removes the Flutter stable release version hack.

The logic only worked on the 'be' branch but if Flutter uses a dev branch hash
they would get a dev release version rather than the hardcoded 2.7.0 version.

This adds a temporary hack causing make_version.py to report 2.5.0 if
the VERSION file's major.minor.patch = 2.5.0 and the channel is be and
--custom_for_pub = flutter. As soon as the VERSION file is bumped on
master, the hack will become a no-op and can be removed.

Previously, if --custom_for_pub was used we used the latest dev tag.
This "best effort" for Dart rolls from bleeding edge, but doesn't make
sense when rolling from other channels that have a proper version in the
VERSION file.

Right now most of the dart SDK's python is compatible with python2
or python3. This change fixes a few of the build scripts to make
that completely true (at least when building the standard build on
Linux). There are only four types of changes:
- Bare `print` statements now use the `print ()` function
- `commands.getoutput` becomes `subprocess.check_output` with `shell=True`
- `xrange` becomes `range`
- `print >> sys.stderr` becomes `sys.stderr.write`
Starts work on addressing (but does not completely fix):

After Clang 6.0, changing the value of a single string can change the
order of symbols in the .rodata section. This confuses Golem's
checks for the equivalence of two binaries.
This change adds a GN flag to omit the git hash and commit time from
the Dart VM's version string to avoid re-running Golem benchmarks on
commits where the only VM change is in the version string.
To use it, pass --gn-args="dart_version_git_info=false" to gn.py
