wifi(implementation): Add unit test framework

We're going to add some non-trivial logic in wifi chip to handle
multiple chip configurations (to support devices with different
capabilities). So, adding a unit test framework in preparation
for testing those changes.

The mocks only mock legacy HAL methods which are in use during chip
configuration & interface creation/deletion.
