Subject: [PATCH] AVRO-3882: [Java][Build] Publish Build Scans to
 develocity.apache.org

Add the Develocity Maven extension and Common Custom User Data
extension so that Maven builds publish a Build Scan to the ASF
Develocity instance when, and only when, the build is authenticated
with an access key. Builds without a key, including fork pull
requests and contributors' local builds, are unaffected.

The Java-focused workflows export DEVELOCITY_ACCESS_KEY from the
secret of the same name. Interop jobs in the other language
workflows are left out. The Develocity build cache stays disabled,
since the build already uses the Apache Maven Build Cache Extension.
