feat: add mcp_config input variable to vscode-desktop-core module (#753)
## Description

Standardizes handling of `mcp` variables in VSCode Desktop-based
modules.
Made modular enough to pave the way for setting other config files than
`mcp_server.json` and `mcp.json`.

## Type of Change

- [ ] New module
- [ ] New template
- [ ] Bug fix
- [x] Feature/enhancement
- [ ] Documentation
- [ ] Other

## Testing & Validation

- [x] Tests pass (`bun test`)
- [x] Code formatted (`bun fmt`)
- [x] Changes tested locally
