Omar Chebib e7d5fee856 change(espcoredump): save RAM space by placing constants in flash
All the log messages of espcoredump component used to be in DRAM, which would
lower the available RAM space for the user application. Since the cache is always
enabled after an exception, constants can be put in flash.
