Arm backend: Rename passes for consistency

[martinlsm]

• Add *Pass suffix for passes missing it
• Add missing _pass suffixes to python files containing passes
• Correct pass name: DecomposeLinearVectorNormPass to DecomposeLinalgVectorNormPass
• Rename ConvertIntPowToMuls to DecomposeIntPowPass
• Rename QuantizeOperatorArguments to QuantizeClampArgumentsPass
