Add some missing package dependencies

Build code transformations can introduce dependencies on packages such
as @wordpress/element and @babel/runtime. These need to be declared if
the package is to function correctly with yarn's p'n'p or pnpm with
hoisting disabled.

- @wordpress/preferences depends on @wordpress/element (fixes #41341)
- @wordpress/reusable-blocks depends on @babel/runtime (fixes #41343)
- @wordpress/viewport depends on @wordpress/element (fixes #41346)
