Bump firmware to 2.4 and cleanup platform code

Rename SOFTWARE_VERSION to kSoftwareVersion and bump the firmware version to "2.4", updating multiple firmware mains to use the new symbol. Remove two Makefile entries (gd32_emac_artnet_pixel_multi symlink and gd32_emac_llrp Makefile). Remove a problematic optimization pragma from crc32.cpp. Add a detailed documentation block to the RTL8201F PHY timing routine (CustomizedTiming) explaining RMSR fields, platform-specific timing adjustments for GD32F4xx, and chosen RX/TX offset values. These changes standardize the version identifier, clarify PHY timing behavior, and clean up platform build files.
