Feature request: Make debugger accessible through Run/Add Configuration...

[torgil]

Currently, the Starlark Debugger can be used by right-clicking a build target in the Bazel Build Targets view and selecting "Build Target with Starlark Debugger".

This above option is currently non-optimal or non-functional for a few scenarios

• Ability to debug a failing query phase
• Multiple variants of arguments to the same target

A proper "launcher" with settings that could be saved in json with the ability to customize bazel commandline should solve this problem.
