types(runtime-core): using intersection type in Readonly<...> breaks JSDoc emit

[johnsoncodehk]

Fix a dts emit regression for v3.5.

Input Component

import { defineComponent } from "vue";

export default defineComponent({
	props: {
		/**
		 * The hello property.
		 */
		hello: {
			type: String,
			default: 'Hello'
		},
	},
});

v3.5.0 emit dts result

declare const _default: import("vue").DefineComponent<import("vue").ExtractPropTypes<{
    /**
     * The hello property.
     */
    hello: {
        type: StringConstructor;
        default: string;
    };
}>, {}, {}, {}, {}, import("vue").ComponentOptionsMixin, import("vue").ComponentOptionsMixin, {}, string, import("vue").PublicProps, Readonly<{
    hello: string;
} & {} & {}>, {
    hello: string;
}, {}, {}, {}, string, import("vue").ComponentProvideOptions, true, {}>;
export default _default;

PR emit dts result

declare const _default: import("vue").DefineComponent<import("vue").ExtractPropTypes<{
    /**
     * The hello property.
     */
    hello: {
        type: StringConstructor;
        default: string;
    };
}>, {}, {}, {}, {}, import("vue").ComponentOptionsMixin, import("vue").ComponentOptionsMixin, {}, string, import("vue").PublicProps, Readonly<import("vue").ExtractPropTypes<{
    /**
     * The hello property.
     */
    hello: {
        type: StringConstructor;
        default: string;
    };
}>> & Readonly<{}>, {
    hello: string;
}, {}, {}, {}, string, import("vue").ComponentProvideOptions, true, {}>;
export default _default;

There seems to be a type breakage in vue-18n ecosystem-ci but I don't think we should block the PR on it. Would still be great to investigate though: https://github.com/vuejs/ecosystem-ci/actions/runs/10701509209/job/29667629360
