feature(ORM): add new APIs

[pga2rn]

Introduction

This PR adds new APIs to ORM:

Applies to ORMBase, ORMThreadPoolBase and AsyncORMThreadPoolBase:

1. add orm_execute: similar to sqlite3.Connection.execute, execute one sqlite statement and return all result in a list.
2. add orm_select_entry: select exactly one entry from the database.

Applies to ORMThreadPoolBase and AsyncORMThreadPoolBase:

1. add orm_pool_shutdown: close the threadpool and optionally close the connections used in the pool.

Other changes:

1. add tests covering the new APIs.
2. orm: minor fix to typing.
3. orm: assign API docstrings from ORMBase to each thread pool variants.
4. typing: now copy_callable_typehint will also copy the __doc__ from source to target.
5. minor update and refinement to the test files.
