GH-48637: [C++][FlightRPC] ODBC: Disable `absl` deadlock detection (#48747)
### Rationale for this change
https://github.com/apache/arrow/issues/48637
Arrow Flight SQL ODBC gets `potential deadlock` error during tests because
this error is happening at Arrow Flight SQL (see
https://github.com/apache/arrow/issues/48714). Arrow doesn't use `absl::Mutex`
directly, and `absl::Mutex` is used by upstream projects gRPC/Protobuf, so
Arrow itself likely did not cause the potential deadlock. We can disable the
deadlock detection for now.
### What changes are included in this PR?
- Disable `absl` deadlock detection inside ODBC, so potential deadlock
detection from upstream projects don't get picked up in the tests.
### Are these changes tested?
- Tested locally on MSVC Windows
### Are there any user-facing changes?
N/A
