Migrate Az.Functions from AutoRest PowerShell v3 to v4

Breaking changes:
- Replaced -IdentityType parameter with -EnableSystemAssignedIdentity
  (Boolean/SwitchParameter) in New-AzFunctionApp and Update-AzFunctionApp
- Replaced -IdentityID parameter with -UserAssignedIdentity (String
  array of ARM resource IDs) in New-AzFunctionApp and Update-AzFunctionApp
- New-AzFunctionApp and Update-AzFunctionApp now support combining
  SystemAssigned and UserAssigned identities in a single call
- Output type property changes: enum types converted to strings,
  arrays converted to Lists (see BreakingChangeIssues.csv)

Bug fixes:
- Fix parameter set conflict between Create and CreateExpanded when
  passing identity params to internal cmdlet
- Fix AppSetting list type (List[Object] to List[INameValuePair])
- Fix error messages to reference new parameter names
- Fix variable typo (siteCofig to siteConfig)
- Add SKU validation guards for Flex Consumption and Container App plans

Tests:
- Added combined SystemAssigned+UserAssigned identity tests for
  New-AzFunctionApp and Update-AzFunctionApp
- Added Update-AzFunctionApp error guard test for Flex Consumption apps
- Updated test assertions for new parameter names and ErrorIds
- Removed 9 auto-generated template test stubs
- All 64 tests pass in both record and playback modes

Other:
- Updated functionAppStacks.json (adds Node.js 24, Python 3.14, Java 25)
- Added HelpMessage attributes for InputObject, DefaultProfile, and
  ResourceGroupName across all custom cmdlets
- Added comment on StorageAccounts_Update remove-operation directive
