Richard 6ee3aafd46 Make wxDateTime::GetAsDOS() work for dates after 2038 ...

Compute the DOS date/time fields from wxDateTime::GetTm() instead of
round-tripping through time_t. This lets representable DOS dates beyond
the 32-bit time_t range, including 2079-04-08, pack correctly while
still rejecting years outside the DOS 1980..2107 range.

Add focused datetime coverage for the DOS minimum, the reported 2079
date, and the DOS maximum.

Fixes #4393.

Closes #26898.
