Re-export PackedDateCreate, PackedTimeCreate, and StrTemplate from MAPL umbrella (#4964)

* Re-export PackedDateCreate, PackedTimeCreate, StrTemplate from MAPL umbrella (fixes #4963)

Add mapl_PackedTimeMod and MAPL_StringTemplate to the mapl_mp_utils
API so that PackedDateCreate, PackedTimeCreate, PackedDateTimeCreate,
and StrTemplate are accessible via USE MAPL, eliminating the need for
client code to reference internal MAPL submodules directly.

* Add CHANGELOG entry for #4963
