Add suppport for ARM CM55 (#494)
* 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.
