fix : Space quota resource destruction bug fix

Fixed space quota deletion logic:
-Terraform-managed space assignments are now removed before deleting the quota.
-Deletion fails if non-Terraform-managed space assignments still exist.
Skipped non-Terraform managed space assignments during deletion to avoid unintended changes.
Refactored repeated code in the resource_security_group_space_bindings.go .
