chore(client): Merge client and engines-core packages (#18969)
* chore(client): Merge client and engines-core packages
Moves most of `engine-core` package into `core/runtime/engine`
subdirectory of the client.
Moves some utitlites from the `engine-core` into various `internals` sub
This allows us to use `internals` helpers within what used to be
`engines-core` code. In the future, it would also allow us to simplify
the code by reusing some of the client-side abstractions.
