refactor(core): resolve_url_or_path and resolve_url_or_path_deprecated (#18170)
This commit changes current "deno_core::resolve_url_or_path" API to
"resolve_url_or_path_deprecated" and adds new "resolve_url_or_path"
API that requires to explicitly pass the directory from which paths
should be resolved to. 

Some of the call sites were updated to use the new API, the reminder
of them will be updated in a follow up PR.

Towards landing https://github.com/denoland/deno/pull/15454
