[PM-31831] fix: add support for overriding commercial SDK (#18863)

* fix: add support for overriding commercial SDK

* fix: only download commercial when needed

* fix: only download OSS SDK for OSS builds and commercial SDK for commercial builds

Previously, the OSS sdk-internal was downloaded and linked for all
build types including commercial, which is wasteful. Now each build
type only downloads the SDK artifact it needs.
