[ci] Pass more information to the signing job (#5403)

Context: 60ab195

Provide additional useful information regarding the build which is
calling the signing job.  When the build definition name and build
number is passed, the signing job will set the build number to reflect
the calling build.  This makes it much more convenient to immediately
tell which build launched the signing job without having to dig into
the logs.

It also leads to better information in our telemetry regarding the calling build.
