Script to convert library to arm/json

[MariusStorhaug]

Change

• Added a tools folder with a script to convert module library to json based arm templates.
  • Removes existing json files
  • Converts bicep to json
  • Optionally removes bicep files.
  • Changes workflow files to use deploy.json instead of deploy.bicep.

Known issues:

• Some workflows use nested_*.bicep files which are left as is after conversion. These will fail if -CleanUp switch is used with script.

Testing instructions:

• Switch to the branch, or copy script to own branch locally.
• From root in repo, run . .\utilities\ConvertTo-ARMTemplate.ps1 -Path . -CleanUp -Verbose.
• Review changes in repo, while discard changes after reviewing if using the subject repo in this PR.
