[Aptos-framework] Add a public function to emit a new block event

[runtian-zhou]

Description

Add a public function to emit a new block event. This is needed for #4037 . The reason is that a genesis writeset will need both a new block event and a new epoch event for it to be committed. As of now, there's no way to emit this new block event which thus prevented any WriteSet scripts to be executed and committed.

Test Plan

Tested this change along side with #4172 by manually pinning the git version to this commit here. Once this PR lands we will be able to run the test in #4172 again and enable the testing there.

Change the PR to use the timestamp from the block. Also changed to use emit_event directly as emit_new_block_event will invoke update_global_time and would fail as this expect a vm signer.
