Review Comment:
A file is decided to be compacted or uncompacted based on comparing its
actual size with the threshold defined in Conf depending on compaction type:
```
HIVE_ICEBERG_MAJOR_COMPACTION_FILE_SIZE_THRESHOLD("hive.iceberg.major.compaction.file.size.threshold",
"96mb",
new SizeValidator(), "Iceberg data file size in megabytes below
which a file needs to be compacted."),
HIVE_ICEBERG_MINOR_COMPACTION_FILE_SIZE_THRESHOLD("hive.iceberg.minor.compaction.file.size.threshold",
"16mb",
new SizeValidator(), "Iceberg data file size in megabytes below
which a file needs to be compacted."),
```
`fileSizeInBytesThreshold` gets the value from these configs depending on
compaction type.
