refactor(pipelines/cd/build-common): remove redundant packaging logic for non-release versions of pd, tidb, and tidb-test (#3626)

Ref https://github.com/PingCAP-QE/ci/issues/3625

* Eliminated unnecessary packaging commands for non-release versions of
pd, tidb, and tidb-test in the build-common.groovy script, streamlining
the packageBinary function.
* For pd & tidb & tidb, all version builds do not include source code
packaging by default, only when NEED_SOURCE_CODE is explicitly
specified.
