[C++][Arrow Flight SQL ODBC] Find co-located TLS certificate

### Describe the enhancement requested

AC:
- ODBC should find the TLS certificate if it is co-located with the driver. The codebase should find module path of the ODBC driver dll and use the module path as default when user does not pass `trustedCerts` in the connection string.
- Suggestion: One possibility is to use `whereami` library for this.
