Handle ARM thumb function symbols.
ARM thumb functions will have the zero bit set to one, which can cause
function name lookups to fail.
Add an ARM special GetFunctionName that handles this condition.
Fix a couple of the function offsets in unit tests.
Bug: 74844137
Test: Ran unit tests.
Test: Ran debuggerd -b on processes on a bullhead device.
