Infineon: Add cyw20829 platform, shared slot feature, json memory map, psoc6 xip
Based in 1.8.0 release of MCUBoot library
This commit adds CYW20829 Infineon platform support with following capabilities:
1. Overwrite and swap upgrade mode support
2. Multi-image with up to 4 images
3. Hardware security counter is supported for CYW20829 platform
Add XIP support for PSOC6 platform - place BOOT slot in external memory and execute it in place using SMIF in XIP mode
and some new features for Infineon devices.
1. Shared upgrade slot feature - use one shared area for upgrade slots of multiple images
2. Memory map defined using JSON file - define memory regions for bootloader and user app in conventional way using JSON file
