Improve logging for the template function atmos.Component. Generate backend config and provider override files in atmos.Component function

[aknysh]

what

• Improve logging for the template function atmos.Component
• Generate backend config and provider override files in atmos.Component function
• Update docs

why

• Add more debugging information and fix issues with the initial implementation of the atmos.Component function when the backend config file backend.tf.json (if enabled in atmos.yaml) and provider overrides file providers_override.tf.json (if configured in the providers section) were not generated, which prevented the function atmos.Component from returning the outputs of the component when executing in GitHub actions

• When the environment variable ATMOS_LOGS_LEVEL is set to Trace, the template function atmos.Component will log the execution flow and the results of template evaluation - useful for debugging

   ATMOS_LOGS_LEVEL=Trace atmos describe component <component> -s <stack>
   ATMOS_LOGS_LEVEL=Trace atmos terraform plan <component> -s <stack>
   ATMOS_LOGS_LEVEL=Trace atmos terraform apply <component> -s <stack>
