Searching for Nargo.toml should not crawl past root

[phated]

Problem

Currently, the function that searches for Nargo.toml will look in every directory up to the root of you filesystem. However, this search should stop at some given root directory (usually the pwd of the nargo process, but maybe a --program-dir passed or the workspace root in the LSP)

Happy Case

The search should stop at some root.
