Remove Relative Path Imports

[stricklandrbls]

I believe the import paths should be aliased now that more components for the extension are communicating with one another i.e, the Data Editor and DFDL Runtime interaction.

I have a working example for the data editor extension that allows importing subdirectories within the data editor source as: import * as clientPanel from '@dataEditor/panel' or import { activate } from '@dataEditor/activation'. The most beneficial would be the components that utilize the MessageCommand from the data editor extension side.

@hdalsania This is partially resolved in #1716

I can go through and ensure that the excessively long import string utilize condensed imports.
