Make sure WDP is completely disabled on Tor windows

[remusao]

Description

Currently, when a user opts-in, the Web Discovery Project will also be initialized in Tor windows. This is unintended and we should add a check similar to https://github.com/brave/brave-core/blob/master/browser/tor/tor_profile_manager.cc#L130 for WDP.

Steps to Reproduce

1. Opt-into WDP in Brave browser.
2. Open a Tor Window
3. Visit brave://inspect tab extensions
4. WDP is initialized (can be seen in console when clicking on inspect

Actual result:

WDP is initialized.

Expected result:

WDP should not be initialized.
