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.)
