[injected-v2.2.2-alpha.2] : Fix - Add functionality to MM getInterface to check provider against all other provider flags

[Adamj1232]

Description

Add functionality to MM getInterface to check provider against all other provider flags.
This is needed in cases such as usage within Brave browser where Brave wallet has both a flag for isMetaMask and isBraveWallet
This added functionality can be added to other wallet interfaces in the case there is collision between provider flags.
