Add clean to mvn calls that can be retried

[nineinchnick]

Description

If mvn crashes for any reason, it might leave behind invalid artifacts, and it'll keep failing in all subsequent runs. All these commands run on an already clean environment, but adding clean in the first run should not add too much overhead. Note that retries were added to handle failures during dependencies download and this will keep working the same.

can you please stitch this into commit message?

@nineinchnick btw is this addressing a problem that may occur, or a problem that has already manifested itself?

@findepi I amended the commit message. I've seen this happening but I can't link to a GHA run. Maven failed with:

Warning: ][warning][gc,alloc] pool-717-thread-2: Retried waiting for GCLocker too often allocating 625002 words
Terminating due to java.lang.OutOfMemoryError: Java heap space

and then retries were failing with:

 Error:  Failed to execute goal org.apache.maven.plugins:maven-shade-plugin:3.2.4:shade (default) on project trino-product-tests-launcher: Error creating shaded jar: error in opening zip file /home/runner/work/trino-lts/trino-lts/testing/trino-product-tests-launcher/target/trino-product-tests-launcher-370-SNAPSHOT.jar -> [Help 1]
