[SPARK-30570][BUILD] Update scalafmt plugin to 1.0.3 with onlyChangedFiles feature

### What changes were proposed in this pull request?
Update the scalafmt plugin to 1.0.3 and use its new onlyChangedFiles feature rather than --diff

### Why are the changes needed?
Older versions of the plugin either didn't work with scala 2.13, or got rid of the --diff argument and didn't allow for formatting only changed files

### Does this PR introduce any user-facing change?
The /dev/scalafmt script no longer passes through arbitrary args, instead using the arg to select scala version.  The issue here is the plugin name literally contains the scala version, and doesn't appear to have a shorter way to refer to it.   If srowen or someone else with better maven-fu has an idea I'm all ears.

### How was this patch tested?
Manually, e.g. edited a file and ran

dev/scalafmt

or

dev/scalafmt 2.13

Closes apache#27279 from koeninger/SPARK-30570.
