Provide IPC URL to CLI from VS Code clones

[d13]

Summary

In the non-bundled version, creates discovery files in temp directory for IDE clone support.

Setup

In settings.json, add the following:

"gitlens.gitkraken.cli.integration.enabled": true
"gitlens.gitkraken.cli.insiders.enabled": true

New CLI integration features - low as it is an additive feature

Currently, if the gitlens.gitkraken.cli.integration.enabled setting is not applied, no new features will appear.
