Also makes the `pub` shell script (and its .bat counterpart)
forward to a `dart __deprecated_pub` command that implements the
old top-level.
This allows us to get rid of pub.dart.snapshot saving ~15 MB in a
unzipped sdk.
The reason for not forwarding directly to `dart pub` is that the
interface is slightly different (for example there is no `dart pub --version`).
The only new commit in pub is: `3c2ce330 Expose toplevel as a command`

When constructing the command line for creating the kernel service
snapshot, the variable `abs_output` actually contains a relative
path, which means that copy/pasting the generated command line fails
if not within the root build directory. This CL fixes that.
Previous revert: https://dart-review.googlesource.com/c/sdk/+/200940
Passes `--depfile-output-filename` with the path relative to the output
folder so that the written depfiles do not contain the absolute file
paths.
ninja only accepts paths relative to the build folder in the .d files.
Manually tested that the dependencies now work with running the
build twice:

Several people have experienced build issues traced back to
target `//utils/dartanalyzer:generate_summary_strong`.
The issue is triggered by the sdk_hash changing with an old
kernel-service snapshot in the out/ folder.
`generate_summary_strong` uses but does not explicitly depend on
the kernel-service, causing the outdated dependency.
This then causes 'Unexpected Kernel SDK Version' when the new dart
binary tried to load the old kernel-service snapshot.
Tested:
1. Clean build of create_sdk at HEAD.
2. Empty `git commit --amend` to modify commit and thus sdk hash.
3. Rebuild of create_sdk (which failed before).

Adds a new SDK hash to kernels and the VM which is optionally checked

This helps catch incompatibilities that are currently causing

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.
