Support path alias for webpack and babel

[ruanyl]

Description

This PR add path alias support for webpack and babel. Previously, path alias only works for importing typescript types.

1. webpack now supports opensearch-dashboards/public path alias
2. Refactor the current in-house path resolution in BundleRefsPlugin to use webpack internal compiler.resolverFactory to work with webpack path alias
3. Introduced babel-plugin-module-resolver to enable path alias support for babel so that we can use path alias in server side code and jest tests.

Examples:

For public code

// before
import { formatUrlWithWorkspaceId } from '../../../../../src/core/public/utils';
// after
import { formatUrlWithWorkspaceId } from 'opensearch-dashboards/public/utils';

For server code

// before
import { fromRoot } from '../../../core/server/utils';
// after
import { fromRoot } from 'opensearch-dashboards/server/utils';

For jest tests:

// before
import { applicationServiceMock } from '../../../src/core/public/mocks';
// after
import { applicationServiceMock } from 'opensearch-dashboards/public/mocks'

can we have some existing code updated to new format? so that we can verify it works during build and also take it as example.
