using MOZMBA as attribution when searching using Bing

[kjozwiak]

Description:

When searching via Brave within iOS, we use MOZMBA as the search attribution. I'm pretty sure this belongs to Mozilla which means any Brave user searching with Bing is generating revenue for Mozilla. @iccub confirmed that we basically use the same code we pulled so I'm pretty sure this belongs to Mozilla.

Steps to Reproduce

1. launch Brave
2. Using Bing, perform a search and you'll notice pc=MOZB&form=MOZMBA being used as the search attribution

Actual result:

Using the following search attribution when using Bing:

Expected result:

Should be using something else other than MOZMBA which belongs to Mozilla.
