Remove ComponentLookup

[Copilot]

ComponentLookup has been dead code for a long time — its componentFor/layoutFor methods are unused by the framework — yet it was still registered into every application and engine as component-lookup:main and exported publicly via @ember/-internals/views.

Changes

• Deleted packages/@ember/-internals/views/lib/component_lookup.ts
• Removed export of ComponentLookup from @ember/-internals/views/index.ts
• Removed import and registry.register('component-lookup:main', ComponentLookup) from @ember/engine/index.ts
• Updated engine and application tests to drop the now-removed component-lookup:main registration assertions
• Cleaned up package.json module map and lib/index.js dist file list entries
