[C++][Gandiva] Reduce dependency on vendored date.h library #51215
Description
Describe the enhancement requested
Follow up on #48593 / #48601 - migrate remaining uses of arrow_vendored::date to arrow::internal::chrono, using std::chrono where supported.
We now partially use std::chrono, but core parsing/formatting, Gandiva, and timezone configuration still
reference vendored code. The vendored timezone implementation is also compiled unconditionally.
We should retain vendored date.h for platforms where we cannot use std::chrono. We should preserve existing behavior and validate formatting edge cases, timezone transitions, etc.
This can be implemented incrementally, by adding required APIs to the existing arrow::internal::chrono shim with a conditional backend.
