[IMP] tool, website, website_sale: move test utils functions

We have multiple ways of simulating a frontend context while running python
tests (mainly during TransactionCase):
  - `MockObject` class from 8557bcfa30
  - `simulate_frontend_context` method from a5a5a57e48
  - `DotDict` from f8efc9a957c28

This commit moves `MockObject` to misc to be reusable and adapt it to be
accessible by dot notation with `DotDict`.

Part of #34396
