Adapt Terraform HCL parsing to system python-hcl2 8.x.
The system python-hcl2 package uses different serialization defaults
than the HCL parser previously bundled with Google Cloud CLI.
Explicitly configure serialization options to strip string quotes,
omit comments, and disable explicit block representation, preserving
the expected output format for Infrastructure Manager and Security
Command Center Terraform processing.
