Bump software version to 2.4; remove crc pragma

Update software version symbol and value: rename SOFTWARE_VERSION to kSoftwareVersion and bump value to "2.4" in firmware-template header, and update usages in gd32_dmx_usb_pro and gd32_rdm_responder mains. Also remove the "-fprefetch-loop-arrays" optimization pragma from lib-clib/src/crc32/crc32.cpp as a minor cleanup.
