Snapshots: move "op_npm_process_state" to "ext/node"

[bartlomieju]

This op should be moved to "ext/node":

deno/cli/ops/mod.rs

Lines 51 to 56 in 9010b8d

	#[op2]
	#[string]
	fn op_npm_process_state(state: &mut OpState) -> Result<String, AnyError> {
	let npm_resolver = state.borrow_mut::<Arc<dyn CliNpmResolver>>();
	Ok(npm_resolver.get_npm_process_state())
	}

To do that we need to move CliNpmResolver::get_npm_process_state to deno_node::NpmResolver. Since it's quite loosely typed (just serializes some data to a string) it should be straightforward.
