Add suppport for ARM CM55 (#494)

Browse source 
* Add supposrt for ARM CM55

* Fix file header

* Remove duplicate code

* Refactor portmacro.h

1. portmacro.h is re-factored into 2 parts - portmacrocommon.h which is
   common to all ARMv8-M ports and portmacro.h which is different for
   different compiler and architecture. This enables us to provide
   Cortex-M55 ports without code duplication.
2. Update copy_files.py so that it copies Cortex-M55 ports correctly -
   all files except portmacro.h are used from Cortex-M33 ports.
