Currently in `SpecificParquetRecordReaderBase` we use deprecated APIs in a
few places from Parquet, such as `readFooter`, `ParquetInputSplit`, `new
ParquetFileReader`, `filterRowGroups`, etc. This replaces these with the newer
APIs. In specific this:
- Replaces `ParquetInputSplit` with `FileSplit`. We never use specific
things in the former such as `rowGroupOffsets` so the swap is pretty simple.
- Removes `readFooter` calls by using `ParquetFileReader.open`
- Replace deprecated `ParquetFileReader` ctor with the newer API which takes
`ParquetReadOptions`.
- Removes the unnecessary handling of case when `rowGroupOffsets` is not
null. It seems this never happens.
### Why are the changes needed?
<!--
Please clarify why the changes are needed. For instance,
1. If you propose a new API, clarify the use case for a new API.
2. If you fix a bug, you can clarify why it is a bug.
-->
The aforementioned APIs were deprecated and is going to be removed at some
point in future. This is to ensure better supportability.
### Does this PR introduce _any_ user-facing change?
<!--
Note that it means *any* user-facing change including all aspects such as
the documentation fix.
If yes, please clarify the previous behavior and the change this PR proposes
- provide the console output, description and/or an example to show the
behavior difference if possible.
If possible, please also clarify if this is a user-facing change compared to
the released Spark versions or within the unreleased branches such as master.
If no, write 'No'.

No
### How was this patch tested?
<!--
If tests were added, say they were added here. Please make sure to add some
test cases that check the changes thoroughly including negative and positive
cases if possible.
If it was tested in a way different from regular unit tests, please clarify
how you tested step by step, ideally copy and paste-able, so that other
reviewers can test and check, and descendants can verify in the future.
If tests were not added, please describe why they were not added and/or why
it was difficult to add.

This is a cleanup and relies on existing tests on the relevant code paths.
