SPARK-17059: Allow FileFormat to specify partition pruning strategy
## What changes were proposed in this pull request?
This is a follow up to changes in #14649 to meet the new codebase changes.
It is slightly different in that it will not filter files explicitly, but it
allows a FileFormat to prune splits (if applicable). This is implemented in
ParquetFileFormat and every other format maintains the same behavior.
## How was this patch tested?
Passing current tests and added two new tests to validate the pruning and
ensure that excessive filtering does not occur on malformed metadata.
Thanks!
