[infra] Split up package:native_assets_cli

[dcharkes]

Closes: #999

Splits up package:native_assets_cli in package:hooks, package:code_assets and package:data_assets.
Renames package:native_assets_builder to package:hooks_runner.

The dependencies are as follows:

• hooks has dev dependencies on code_assets and data_assets because all the integration tests use these asset types.
• hooks_runner has a dependency on code_assets due to the kernel-encoding KernelAssets which is used to bundle the code-assets asset-mapping in various SDKs.
• hooks_runner has a dev dependency on data_assets because the integration tests use it.

Versions:

• The split up packages continue numbering from the original version. (It doesn't really matter, we'll need to go to 1.0.0 in the future anyway.)

Internal package structure:

• This PR does not reorganize packages. It moves the files exactly to the same path. This could use cleanup, but let's try to get this PR as small as possible.

CI:

• Two workflows are combined. (This could likely use some cleanup, especially trying to collect coverage across all packages in the workspace instead of a single package at the time.)

Publishing:

• These packages will now need their autopublishing set up. I'll do this after we bump the version to non-wip.

Rolling:

• This will need to be rolled into the Dart and Flutter SDKs. Changing the dependencies there and fixing whatever test setup explicitly mentioning the package names.

LGTM

[goderbauer]

Should pkg:code_assets and pkg:data_assets be added to this list of packages for completeness?

[goderbauer]

nit: there's a verb ("using"?) missing here after "be".
