[v2] [DEP0169] DeprecationWarning: url.parse() behavior is not standardized and prone to errors

autorest v2 may fail with this error on node 24:

> [DEP0169] DeprecationWarning: `url.parse()` behavior is not standardized and prone to errors that have security implications. Use the WHATWG URL API instead. CVEs are not issued for `url.parse()` vulnerabilities.

Fix would be to change this code, to use the new `URL` api:

https://github.com/Azure/autorest/blob/50330797d3f0dfcd233967544b66f541a327ba74/src/autorest-core/lib/ref/uri.ts#L14

Start at src/autorest-core/lib/ref/uri.ts around line 14, as identified in the issue. Read how the current URL parsing is used, then update it to use the WHATWG URL API instead. Done means the Node 24 deprecation warning is no longer triggered by this code.
