Cleanup: material API naming

- Use 'BKE_object_material_*', 'BKE_id_material_*' prefix
  for functions that operate on Object and ID types.
- Use '_len' suffix for length (matching BLI naming).
- Use '_p' suffix for functions that return a pointer to values
  where the value would typically be returned.

Functions renamed:

- BKE_object_material_resize      was BKE_material_resize_object
- BKE_object_material_remap       was BKE_material_remap_object
- BKE_object_material_remap_calc  was BKE_material_remap_object_calc

- BKE_object_material_array_p     was BKE_object_material_array
- BKE_object_material_len_p       was BKE_object_material_num
- BKE_id_material_array_p         was BKE_id_material_array
- BKE_id_material_len_p           was BKE_id_material_num

- BKE_id_material_resize          was BKE_material_resize_id
- BKE_id_material_append          was BKE_material_append_id
- BKE_id_material_pop             was BKE_material_pop_id
- BKE_id_material_clear           was BKE_material_clear_id
