Add method to generate a cell phone number to pt-BR
Faker doesn't have a function to generate a cellphone to Brazilian.

Steps to reproduce
Create fake instance using localization "pt_BR"
Call fake.msisdn() or fake.phone_number()
Expected behavior
It should generate a cell phone number.

Actual behavior
Sometimes these methods return a "residential" numbers.

Reference difference between cell phones and residential numbers:
