[SPARK-32813][SQL] Get default config of ParquetSource vectorized reader if no active SparkSession
### What changes were proposed in this pull request?
If no active SparkSession is available, let `FileSourceScanExec.needsUnsafeRowConversion` look at default SQL config of ParquetSource vectorized reader instead of failing the query execution.
### Why are the changes needed?
Fix a bug that if no active SparkSession is available, file-based data source scan for Parquet Source will throw exception.
### Does this PR introduce _any_ user-facing change?
Yes, this change fixes the bug.
### How was this patch tested?
Unit test.
Closes #29667 from viirya/SPARK-32813.
