ArmPkg/ArmExceptionLib: Follow new CpuExceptionHandlerLib APIs 

CpuExceptionHandlerLib has been refactored with following changes:
1. Removed InitializeCpuInterruptHandlers in 2a09527ebc
2. Removed InitializeCpuExceptionHandlersEx and
   added InitializeSeparateExceptionStacks in e7abb94d1f

The patch updates ARM version of CpuExceptionHandlerLib to follow
the API changes.

The functionality to ARM platforms should be none.
