URL: https://github.com/apache/hudi/pull/12622
### Change Logs
Created a new file format `HoodieFileGroupReaderBasedFileFormat` to support
multiple base file formats, which is guarded by the existing configuration. The
main change that we do is to
1. create a class SparkOrcReaders for Spark3.5, Spark3.4 and Spark3.3.
2. use a map to contain both orc and parquet readers and pass it to Spark
file group reader.
The orc file reader implementation is based on Spark orc reader
implemenation.
### Impact
Support multiple base file format: orc and parquet for Spark3.3, Spark3.4
and Spark3.5
### Risk level (write none, low medium or high below)
Medium.
