Make policy definition and assignment display names generic

Remove hardcoded license type references from policy displayName
and description. The actual target license type is controlled by
parameters at assignment time, so the definition metadata should
not imply a specific value.

Changes:
- azurepolicy.json: displayName and description now use generic
  'Configure Arc-enabled SQL Server license type' wording
- deployment.ps1: collapsed the PAYG/SA conditional display name
  logic into a single generic label per platform
