Describe the bug
The GPU ORC reader returns the wrong pre-Gregorian date when reading the Spark
2.4 compatibility resource. Spark CPU returns 1200-01-01; GPU returns
1200-01-08. The mismatch reproduces in V1 and V2 with both row and vectorized
ORC reader settings.
Steps/code to reproduce
Build the exact PR head, then use Spark 3.3.0 and the complete RAPIDS UT
configuration:

Expected behavior
GPU should return 1200-01-01, matching Spark CPU's Spark 2.4 ORC calendar
compatibility behavior.
