### What changes were proposed in this pull request?
Refactors the base Throwable trait `SparkError.scala` (introduced in SPARK-34920) an interface `SparkThrowable.java`.
### Why are the changes needed?
- Renaming `SparkError` to `SparkThrowable` better reflect sthat this is the base interface for both `Exception` and `Error`
- Migrating to Java maximizes its extensibility
### Does this PR introduce _any_ user-facing change?
Yes; the base trait has been renamed and the accessor methods have changed (eg. `sqlState` -> `getSqlState()`).
### How was this patch tested?
Unit tests.
Closes#33164 from karenfeng/SPARK-35958.

This PR proposes to improve the Github template for better and faster review iterations and better interactions between PR authors and reviewers.
As suggested in the the [dev mailing list](http://apache-spark-developers-list.1001551.n3.nabble.com/DISCUSS-New-sections-in-Github-Pull-Request-description-template-td27527.html), this PR referred [Kubernates' PR template](https://raw.githubusercontent.com/kubernetes/kubernetes/master/.github/PULL_REQUEST_TEMPLATE.md).

Currently, many PR descriptions are poorly formatted, which causes some overheads between PR authors and reviewers.
There are multiple problems by those poorly formatted PR descriptions:
- Some PRs still write single line in PR description with 500+- code changes in a critical path.
- Some PRs do not describe behaviour changes and reviewers need to find and document.
- Some PRs are hard to review without outlines but they are not mentioned sometimes.
- Spark is being old and sometimes we need to track the history deep. Due to poorly formatted PR description, sometimes it requires to read whole codes of whole commit histories to find the root cause of a bug.
- Reviews take a while but the number of PR still grows.
This PR targets to alleviate the problems and situation.
### Does this PR introduce any user-facing change?
<!--
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 no, write 'No'.
