tracing/events: add missing type info of dynamic arrays

The format file doesn't contain enough information for
__dynamic_array/__string. The type name is missing.

Before:
  # cat format:
  name: irq_handler_entry
  ...
          field:__data_loc name;  offset:16;      size:2;

After:
  # cat format:
  name: irq_handler_entry
  ...
          field:__data_loc char[] name;  offset:16;      size:2;
