This commit moves all the functionality related to the current interrupt parser into gen_isr_tables_parser_carrays.py file. The new parser file gen_isr_tables_parser_local.py file is implemented with the new parser that. Additional information added to the generated interrupt header that contains data required by the new parser. Signed-off-by: Radosław Koppel <radoslaw.koppel@nordicsemi.no>
