Linter rule to enforce "strict" keyword order

Params and outputs should be grouped together, params should be at the top, outputs should either be underneath params or at the bottom of the file.

Open question whether this should also enforce strict ordering of `module`, `resource`, or `var`.

The issue names no files, tests, or entry points. First clarify whether ordering applies only to params and outputs or also to module, resource, and var; done means the linter consistently enforces the agreed ordering.
