Describe the enhancement requested

As one of the follow-ups to #36026, apache/orc#1882 got merged into orc 2.0.1, which will use conda(-forge)'s tzdata also on windows, even if the TZDIR environment variable is not being set (inserting that variable into all user environments would have been very intrusive).

Based on this new functionality, I've successfully added orc-on-python support to arrow v13-v15, but some of the other checks introduced in the context of #36026 now fail in conda-forge/pyarrow-feedstock#122, because they haven't yet been taught to allow the case that orc>=2.0.1 now handles.

Component(s)

C++, Packaging, Python

GH-41755: [C++][ORC] Ensure setting detected ORC version (#41767)
ff9921f 
`FindorcAlt.cmake` doesn't set `orcAlt_VERSION` when it finds ORC by `find_library()`/`find_path()`. If `orcAlt_VERSION` isn't set, ORC version detection by caller is failed.

`cpp/src/arrow/adapters/orc/adapter.cc` uses detected ORC version. If detected ORC version isn't correct, needless time zone database check is used.

Deployed in conda-forge through conda-forge/arrow-cpp-feedstock#1424 and confirmed as working in conda-forge/pyarrow-feedstock#122
