Add timezone and use_utc parameters into RegisterTortoise class.

[Abeautifulsnow]

Description

A detailed description can be found here: #1632

Motivation and Context

There are no timezone and utc configurations which can be applied to RegisterTortoise class when using db_url to initialize a sql connection. I've made them available in RegisterTortoise, allowing users to conveniently specify these settings.

How Has This Been Tested?

There are no side effects on other areas of the code. It just introduces two parameters within the RegisterTortoise. I have tested it within my project, and it works with these settings specified. #1632

And can also be tested with:

cd examples/fastapi && PYTHONPATH=. pytest _tests.py

I have also added test cases for the modified parts and passed the self-test.

Ummm... It seems I know where the problem lies. My two test assertions timezones are both based on Asia/Shanghai. Then where is the timezone of the CI test environment? Or maybe I should add more code to adjust the timezone to ensure the test passes?

Yeah, you would need to somehow modify it, so it doesn't rely on what environment it is, as github action do not give any guarantees regarding their timezones

The changes has been Done! @abondar

It seems the issue is due to other test files, not my own. Could you please check it out? Thank you.
