[Az.Functions] Add Flex Consumption support and upgrade to Autorest 4.x

[Francisco-Gamino]

Description

The PR contains the following changes:

• Upgraded Az.Functions to Autorest 4.x
  Resolves [Functions] Upgrade module autorest.powershell v4 #24403
  This upgrade introduces changes to internal types for models generated by Autorest, e.g., new models
  Microsoft.Azure.PowerShell.Cmdlets.Functions.Models.IGeoRegion instead of
  Microsoft.Azure.PowerShell.Cmdlets.Functions.Models.Api20231201.IGeoRegion.

• Updated Az.Functions helpers:
  1) AppInsights helper (src/helpers/AppInsights/readme.noprofile.md) updated to build from the main branch. Previously, it was building from https://github.com/Azure/azure-rest-api-specs/blob/e0d9ceb1ca85e76a31b8496201499a7312824c09, but I needed a version that returns the APPLICATIONINSIGHTS_CONNECTION_STRING.
  2) Storage helper (src/helpers/Storage/readme.noprofile.md) updated to expose Blob container cmdlets, enabling creation, retrieval, and removal of blob containers. These are required to set deployment options for a Flex Consumption app.

• Added support for creating Flex Consumption function apps:
  Resolves [Functions] Add support to create Flex Consumption function apps #24349
  1) Updated Get-AzFunctionAppAvailableLocation PlanType to include FlexConsumption.
  - Added ZoneRedundant to list locations where zone redundancy is supported (currently applies only to Flex Consumption).
  2) Added Get-AzFunctionAppFlexConsumptionRuntime, a new cmdlet to retrieve Flex Consumption function app runtimes supported at a specified location.
  3) Added a new parameter set to New-AzFunctionApp to support creating Flex Consumption function apps.
  - Added regression tests for Flex Consumption scenarios.
