After #23511, the assert in getJSDocHost throws when checking a type reference in a jsdoc type literal:

function PluginFunction() {
}
/**
 * @param {object} options Options for the profiled fn.
 // assert here: this @param's parent is the options tag, not the entire comment
 * @param {PluginFunction} options.fn Plugin function
 * @returns {*} Chainable hooked function.
 */
const makeNewProfiledTapFn = ({ fn }) => {
};

The problem is that getJSDocHost doesn't work with param tags that are nested inside a jsdoc type literal. This PR makes getJSDocHost walk up through jsdoc type literals before getting the host.

Found by compiling webpack with typescript from master.

Fixes #23574
