nguymin4/improve types

[nguymin4]

• Improve type support for analytic functions (See tests for more detail)
• Extract common interfaces for tsd

Important note: I intended to migrate analytic-function-types testing to tsd but I found a problem with the tsd library
For example

  expectType<Pick<User, 'id'>>(
    await knex<User>('users').select('foo')
  );

I expect this test fails but the test somehow passes. I think this is a tsd issue. Thus we need to be more careful before migrating from dtslint to tsd. I will try to debug this if I have time but in my opinion dtslint is still doing a good job for us
