[Feature]: Custom implementation of OpenTofu's recursive templatefile function.

[skyzyx]

What functionality would you like to see?

Backport for Terraform usage.

I'm certain that @cam72cam did an excellent job implementing this inside of OpenTofu (absolutely no shade). I'm interested in trying my hand at implementing this same functionality using a queue and a loop instead of with recursion — more out of curiosity than anything.

This is the nice thing about not having to be constrained by Terraform's early implementation.
