[FEATURE] add source generator meta to generated comment

[delconis]

Is your feature request related to a problem? Please describe.
When reviewing generated code, it's hard to determine which parent stack generated the item

Describe the solution you'd like
I would like to see the current generated message
// TERRAMATE: GENERATED AUTOMATICALLY DO NOT EDIT

To include the invoking generator that created it.
// TERRAMATE: "dev/app/stack.tm.hcl" GENERATED AUTOMATICALLY DO NOT EDIT

Describe alternatives you've considered
Some alternatives would be a way to list all the generated files in a given stack via cli terramate generate --list --chdir dev/app where the output might look like, and list would force and output for each generated item in the stack regardless if there is a modification.

Code generation report

Successes:

[ ] /dev/app
  [ ] provider.tf - Generated from (dev/stack.tm.hcl)
  [ ] backend.tf - Generated from (dev/app/stack.tm.hcl)

Hi @delconis

Have you tried the terramate debug show generate-origins?
For each generated file, it shows the file and line/column where it comes from.

Let me know if it helps you.

Fun fact: Terramate used to include the file name in the header but it caused too many stacks being triggered for changes (when using tm run --changed ...) whenever someone refactored the generated file names. See here the PR that removed it: #710
