[native_assets_builder] Take packageLayout for build and dryRun

[dcharkes]

Enable using PackageLayout in build and run from NativeAssetsBuildRunner, so that does not require reading and reparsing the package config file.

Follow up of:

• PackageLayout constructor for already parsed PackageConfig #126

That PR only covered the code paths in flutter_tools using PackageLayout.packagesWithNativeAssets, this also should cover the paths doing the actual builds.

(Note that flutter_tools requires published dependencies, hence we just land small PRs here and publish right away.)

Context:

• Regression in compilation time due to native asset bundling flutter/flutter#134427

[coveralls]

coverage: 98.189%. remained the same when pulling ff89580 on package-layout-2 into a7cd31e on main.
