Expose backend API to IDE (#10442)

Move `Backend` and supporting APIs from `dashboard` to `enso-common`.

Closes #10400.

# Important Notes
- The utility modules required by `Backend` have been moved to `enso-common`. Those defining general-purpose helpers for working with standard types are now in a submodule `utilities/data` to match the IDE organization; in the future we can merge them with the `util/data` gui2 subtree. Moved utilities are reexported from their dashboard locations, so that moved and not-yet-moved modules can be imported consistently.
- The `text` module has been moved to `enso-common`; the IDE doesn't have any localization mechanism yet, so we can share this one.
