- [Low] The newly defined macro __DDEBUG_ARRAY_SIZE is unused because the array size calculation is manually open-coded.

dyndbg: drop NUM_TYPE_ARGS

This commit removes the NUM_TYPE_ARGS macro and replaces it with an array
size calculation. The commit message mentions adding a new local macro named
__DDEBUG_ARRAY_SIZE to handle this without causing include conflicts.

[Severity: Low]
This isn't a bug, but should this line use the new __DDEBUG_ARRAY_SIZE macro
introduced above? The calculation appears to be manually open-coded here,
leaving the newly defined macro unused.
