Add a URL builder class to urllib

[KaiTomotake]

Feature or enhancement

Proposal:

Currently, when building URLs using the Python standard library, it is necessary to combine functions such as urljoin and urlencode and define a custom helper class. This requires additional boilerplate and effort.

from urllib.parse import urljoin, urlencode

base_url = urljoin("https://example.com", "search")
params = {"q": "python", "page": 1}
full_url = f"{base_url}?{urlencode(params)}"

I propose providing a dedicated class that makes it easy to construct URLs in a clear and structured way.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
