feat(types): enhanced defineComponent inference

[johnsoncodehk]

This PR is all about improving the implementations of defineComponent type inference. It's not a complete rewrite because we can't aggressively rewrite or remove existing types/interfaces to maintain backward compatibility (if we have plans for Vue 4 we can revisit that.)

Improvements / Changes

• TS completion in component options is 40% faster
• The "this" type in data and props options is more accurate
• New DefineComponent2 type passes the structured component options type parameter as is, which streamlined .d.ts output on tsc emit: props types are now printed as is to .d.ts, same types are no longer serialized to multiple parameters in DefineComponent (reduce about 35% code in naive-ui .d.ts)
• Tsc performance improved by about 8% in elk repo
• Prop options (type, required, default, validator) can now navigate to TS definitions
• emits: {} is now correctly handled as an empty event set
• Simplified mixins, extends options inference (no longer using ComponentOptionsMixin intermediate type)
• Simplify h function overloads (remove dependency on helper types such as DefineComponent, ConcreteComponent, etc.)

Sorry to bother but will this be added to 3.6?
Asking in case it's lost down the PRs list as it isn't added to Next Minor (view)
