debugobjects: Fix the compilation attributes of some global variables
1. Both debug_objects_pool_min_level and debug_objects_pool_size are
read-only after initialization, change attribute '__read_mostly' to
'__ro_after_init', and remove '__data_racy'.
2. Many global variables are read in the debug_stats_show() function, but
didn't mask KCSAN's detection. Add '__data_racy' for them.
