Add support for class renaming via bytecode

[samartnik]

Description

To avoid majority of patches in Android xml resources, we should explore the possibility of renaming upstream class to something else and renaming Brave's version of that class to upstream's name. In theory it should pick up Brave's class with upsteam's name in xmls and no other patching will be required. This commit can be used as a starting point samartnik/brave-core@20266a5
