refactor: move "pathFromURL" to deno_web extension (#18037)
This API is required by several extensions like "ext/node", "ext/ffi"
and also FS APIs that we want to move to a separate crate. Because 
of that "pathFromURL" API was moved to "deno_web" extension so
other extension crates can rely on it.
