[KYUUBI #6297] Package Spark SQL engine both Scala 2.12 and 2.13

# 🔍 Description
## Issue References 🔗

This pull request fixes #6297

## Describe Your Solution 🔧

Here are my main modifications:
1. In the `build/dist` file, I added an additional packaging command that detects the version of `SCALA_VERSION`. If it is version 2.12, then it will additionally package version 2.13, otherwise it will package version 2.12
2. In the section of `# Copy spark engines`, the Jar packages of versions 2.12 and 2.13 will be moved to `$DISTDIR/externals/engines/spark/`

This is my first time submitting a PR, so there may be many unfamiliar areas, and I don't know if my changes meet the needs of the community. More guidance may be needed. When testing locally, it was able to be packaged successfully
