feat: Implement extension boot refactor with prebuild approach

- Modified prebuild.js to generate extension shims in app/extensions/
- Generate extension-loaders.js with dynamic import map
- Added ember-auto-import allowAppImports configuration
- Extension setup code is now code-split into separate chunks
- Removed FleetbaseExtensionsIndexer in favor of prebuild generation
- Added generated files to .gitignore

Successfully tested: extension code is code-split into separate chunk
(chunk.app_extensions_fleetops_js.*.js)
