windocker: Figure out how to use longer (original) names for the pipelines

[sxa]

As per the notes in #3286 (comment) I had the reduce the job name to windbld instead of the more usual jdk21u-windows-x64-temurin style format in order to avoid exceeding path lengths. We will need to figure out a solution to this before the windows container builds can be fully integrated into the pipelines.

We have had to take this into account in the past and shorten things. I'll also note that F:\workspace is used on some of our machines instead of F:\ws and that seems to work ok, so we also need to understand if this is an extra limitation which is specific to containers. Noting also that we don't seem to be able to use a separate workspace drive like F: which isn't already in the container.

Ref: #1284 (comment) and the associated PR adoptium/temurin-build#1724 which changed
We force the workspace to C:/workspace if TARGET_OS=windows in order to shorten the path lengths. This does not appear to be taking effect on the docker builds (probably a good thing since C:\workspace is not in a shared location so it wouldn't work properly - we should perhaps aim for C:\jw\ws in this case ...)

The above change to the workspace directory is in an else section which only takes place if the DOCKER_IMAGE variable is not set so this should be relatively simple to resolve, and also resolve in a way that I can use a shared folder C:\jw\ws instead of C:\workspace :-)
