/**
     * Gets combined flags of a `symbol` and all alias targets it resolves to. `resolveAlias`
     * is typically recursive over chains of aliases, but stops mid-chain if an alias is merged
     * with another exported symbol, e.g.
     * ```ts
     * // a.ts
     * export const a = 0;
     * // b.ts
     * export { a } from "./a";
     * export type a = number;
     * // c.ts
     * import { a } from "./b";
     * ```
     * Calling `resolveAlias` on the `a` in c.ts would stop at the merged symbol exported
     * from b.ts, even though there is still more alias to resolve. Consequently, if we were
     * trying to determine if the `a` in c.ts has a value meaning, looking at the flags on
     * the local symbol and on the symbol returned by `resolveAlias` is not enough.
     * @returns SymbolFlags.All if `symbol` is an alias that ultimately resolves to `unknown`;
     * combined flags of all alias targets otherwise.
