Split monolithic state into multiple entities

Split the current Module struct into three smaller structs: Module, Vars, Common (names TBD)

• Modules
  • Directory Path
  • Collected Reference Targets
  • Collected Reference Origins
  • Parsed Module Files
  • Diagnostics for Module Files
  • Metadata
• Vars
  • Directory Path
  • Collected Variable Definition Reference Origins
  • Parsed Variable Definition Files
  • Diagnostics for Variable Definition Files
• Common
  • Directory Path
  • Module Manifest (parsed .terraform/modules/modules.json)
  • Installed Terraform Version
  • Installed Providers

In the future this will allow us to create more state structs for more languages, like test or stacks.
