refactor: apply future type hints style

[waketzheng]

Description

1. Does not change any code logic
2. Add extend-select for ruff lint

    "FA",     # https://docs.astral.sh/ruff/rules/#flake8-future-annotations-fa
    "UP",     # https://docs.astral.sh/ruff/rules/#pyupgrade-up
    "RUF100", # https://docs.astral.sh/ruff/rules/#ruff-specific-rules-ruf

3. Run the following script to auto add from __future__ import annotations:

#!/usr/bin/env python
"""
Auto add 'from __future__ import annotations' to py files that imports `typing`
"""

from __future__ import annotations

import os
from pathlib import Path


def main() -> None:
    t = "from __future__ import annotations"
    package = Path(__file__).parent.name.replace("tortoise-orm", "tortoise")
    total = updated = 0
    for name in (package, "tests", "examples", "conftest.py"):
        if not (d := Path(name)).exists():
            print(f"Skip {d} as it not exists")
            continue
        for p in [d] if d.is_file() else d.rglob("*.py"):
            total += 1
            if t in (s := p.read_text()) or ("from typing " not in s and "import typing" not in s):
                continue
            updated += 1
            lines = s.splitlines()
            index = 0
            doc = False
            for idx, one in enumerate(lines):
                if one.startswith("#"):
                    continue
                if one.startswith('"""') or one.startswith("'''"):
                    if len(one) > 3:
                        # One line document
                        continue
                    if not doc:
                        doc = True
                        continue
                    doc = False
                    index = idx + 1
                    break
                elif not doc:
                    index = idx
                    break
            lines.insert(index, t)
            p.write_text(os.linesep.join(lines + [""]))
            print(f"Inject '{t}' into {p} at line {index + 1}")
    if not total:
        print("No target found, please check current directory!")
    elif not updated:
        print(f"None of file need to update({total} files found)")
    else:
        print(f"Summary: {total = }; {updated = }")


if __name__ == "__main__":
    main()

4. Execute ruff check --fix --unsafe-fixes tortoise examples tests conftest.py to reformat
5. Install autoflake and run its shell command to remove unused imports:
   autoflake --remove-all-unused-imports -i -r tortoise examples tests conftest.py
6. Reformat by make _style
7. Change make lint to be make style+make check
8. Refactor tortoise/backends/base/schema_generator.py::BaseSchemaGenerator::_get_table_sql to reduce complexity (which was complained by codacy)
