Cleanup Workspace - Github Action

Simply removes all files from the root directory.

This is useful to clean residue in workspaces from previous self-hosted builds which can have a mix of root owned files that are not able to be removed by the user running the action.

It seems the checkout action is run as the host user, but files created by other actions is run by root. The subsequent checkout is unable to remove the files created from the previous run. Action Runners does not automatically clean up.

This action can also be used in the end of workflow to clear all files and free up diskspace in self-hosted runner.
