Prefix include guards with GD32; rename UUID files

Standardize header include guards to GD32_<NAME>_H_ across multiple headers (panelled.h, serialnumber.h, timing.h, uart0.h, watchdog.h) to avoid macro collisions. Move/rename hal_uuid.h to lib-gd32/include/uuid.h and relocate uuid.cpp to lib-gd32/src/uuid.cpp; bump copyright years and remove the hal namespace wrapping. Minor style/formatting tweaks (IWYU pragma for gd32.h, small function/brace formatting). These changes unify guard naming and consolidate the UUID implementation under lib-gd32.
