Airgap Tethys when STATICFILES_USE_NPM is true (#1300)

* Add select2-bootstrap-5-theme as a static dependency

- Register it in vendor_static_dependencies so it can be served locally
- Replace the hardcoded jsDelivr CDN link in map_layout.html with the vendored
  dependency, so the Select2 Bootstrap 5 theme works air-gapped

* Use local plotly in map layout when STATICFILES_USE_NPM is True

- Add staticfiles_use_npm to map layout's context dictionary
- Use staticfiles_use_npm to determine when to use the local plotly instead of the CDN provided plotly
- Continue to allow specifying the version of plotly in the controller when staticfiles_use_npm is False
- Local plotly is inlined from the installed Python package via the plotly_view gizmo dependency

* Add fontawesome as a static dependency

- Register it in vendor_static_dependencies so it can be served locally
- Replace the hardcoded Font Awesome CDN link (use.fontawesome.com) in
  tethys_layout.html with the vendored dependency, so fontawesome works air-gapped
- Online, Font Awesome now loads from jsDelivr (the vendored dependency's CDN) instead of use.fontawesome.com

* Add dependency_script and dependency_link template tags

- Let app templates load third-party JS/CSS that is served from the app's local
  node_modules when STATICFILES_USE_NPM is True, and from the CDN otherwise, so
  apps work air-gapped without a manual local/CDN toggle
- Derive the local path automatically from jsDelivr and unpkg npm URLs, so authors
  only pass the CDN URL they would normally use
- Accept an optional local_path for CDNs that can't be auto-derived (e.g. cdnjs)
- Register the tags in the tethys template tag library so they're available via {% load tethys %}

* Fall back to the installed version when the requested version is unavailable offline

- In get_custom_version_url, serve the installed (default) version locally instead
  of the CDN when STATICFILES_USE_NPM is True and a different version is requested
- T... (continued)
