Build complete workspace when buildOnSave is set to workspace

[sandy081]

Testing microsoft/vscode#33297

When the setting go.buildOnSave is set to workspace, in a multi-root workspace it is expected to build the complete workspace instead of just the workspace folder. I see it was mentioned expected but this can be changed.

Here is the use case: In the sample MR set up I have two root folders hello and stringutil. I wanted to configure settings in stringutil folder that on changes in this folder, I would like to build all other workspace folders too.

Closing this as "as-designed"
For now, in multi-root set-up, in the Go extension workspace in build/lint/vet on save settings will not mean the entire workspace. Build/Lint/Vetting the entire workspace will get expensive and there are no great benefits for the same.

We will re-visit if and when there is user feedback in this direction
