[FEATURE] Support Terraform auto-complete in generate_hcl blocks in VS Code

[cwe1ss]

Is your feature request related to a problem? Please describe. In many of my stacks, I'm calling just one Terraform module with some of the values coming from Terramate globals.

If I define my module call in a main.tf, I will get Terraform auto-complete (which I really need for usability), but I will have to convert my Terramate globals into Terraform locals (via some generate_hcl block). This seems like a redundant step.

If I define my module call directly in my stack.tm.hcl through a generate_hcl-block, I can access all my Terramate globals (which is great), but I don't have any auto-complete for the Terraform module, so I constantly have to look at the module documentation, or call terramate generate and look at the generated code.

Describe the solution you'd like The Terramate VS Code extension supports Terraform auto-completion in generate_hcl-blocks. It could look at the extension of the generated file name and somehow redirect the content block to its original VS Code extension for auto-complete.

Ideally, this would also support auto-complete for the Terramate globals. :)

Additional context Maybe possible using the Embedded Languages-features of VS Code!?

This would dramatically increase the DX for code generation.
