[SPARK-55273][SQL] Replace ParquetFileReader.open().getFooter() with readFooter() to avoid unnecessary operations in ParquetFooterReader

### What changes were proposed in this pull request?
This pr replace `ParquetFileReader.open().getFooter()` with `ParquetFileReader.readFooter()` to avoid unnecessary operations in `ParquetFooterReader`

### Why are the changes needed?
Compared to `ParquetFileReader.readFooter()`, `ParquetFileReader.open()` performs more operations as follows:

```
    this.converter = new ParquetMetadataConverter(options);
    this.file = file;
    this.f = f;
    this.options = options;
    this.footer = footer;

    this.fileMetaData = footer.getFileMetaData();
    this.fileDecryptor = fileMetaData.getFileDecryptor(); // must be called before filterRowGroups!
    if (null != fileDecryptor && fileDecryptor.plaintextFile()) {
      this.fileDecryptor = null; // Plaintext file. No need in decryptor
    }

    try {
      this.blocks = filterRowGroups(footer.getBlocks());
    } catch (Exception e) {
      // In case that filterRowGroups throws an exception in the constructor, the new stream
      // should be closed. Otherwise, there's no way to close this outside.
      f.close();
      throw e;
    }
    this.blockIndexStores = listWithNulls(this.blocks.size());
    this.blockRowRanges = listWithNulls(this.blocks.size());
    for (ColumnDescriptor col : footer.getFileMetaData().getSchema().getColumns()) {
      paths.put(ColumnPath.get(col.getPath()), col);
    }

    if (options.usePageChecksumVerification()) {
      this.crc = new CRC32();
      this.crcAllocator = ReusingByteBufferAllocator.strict(options.getAllocator());
    } else {
      this.crc = null;
      this.crcAllocator = null;
    }
```

And these operations can be omitted for the requirement of `readFooter`.
