/**
* Normalize the `path`, resolving `'..'` and `'.'` segments.
* Note that resolving these segments does not necessarily mean that all will be eliminated.
* A `'..'` at the top-level will be preserved, and an empty path is canonically `'.'`.
*
* @example Usage
* ```ts
* import { normalize } from "@std/path/posix/normalize";
* import { assertEquals } from "@std/assert";
*
* assertEquals(normalize("/foo/bar//baz/asdf/quux/.."), "/foo/bar/baz/asdf");
* assertEquals(normalize(new URL("file:///foo/bar//baz/asdf/quux/..")), "/foo/bar/baz/asdf/");
* ```
*
* @example Working with URLs
*
* Note: This function will remove the double slashes from a URL's scheme.
* Hence, do not pass a full URL to this function. Instead, pass the pathname of
* the URL.
*
* ```ts
* import { normalize } from "@std/path/posix/normalize";
* import { assertEquals } from "@std/assert";
*
* const url = new URL("https://deno.land");
* url.pathname = normalize("//std//assert//.//mod.ts");
* assertEquals(url.href, "https://deno.land/std/assert/mod.ts");
*
* url.pathname = normalize("std/assert/../async/retry.ts");
* assertEquals(url.href, "https://deno.land/std/async/retry.ts");
* ```
*
* @param path The path to normalize.
* @returns The normalized path.
