889807dfda .Net: Update Microsoft.Extensions.AI dependencies to 10.3.0 and OpenAI SDK to 2.8.0 (#13544)
### Motivation and Context

Updates Microsoft.Extensions.AI packages to latest stable releases
(10.3.0) and OpenAI SDK to 2.8.0. The new versions require transitive
dependency updates and fixing breaking type renames in the OpenAI
Responses API. Additionally, the new `ChatOptions.Reasoning` property is
now mapped from `PromptExecutionSettings` and used in samples instead of
`RawRepresentationFactory`.

### Description

**Package Updates:**
- `Microsoft.Extensions.AI` and `Microsoft.Extensions.AI.Abstractions`:
10.2.0 → 10.3.0
- `Microsoft.Extensions.AI.OpenAI`: 10.0.1-preview → 10.3.0 (stable)
- `OpenAI`: 2.7.0 → 2.8.0
- `Azure.AI.OpenAI`: 2.7.0-beta.2 → 2.8.0-beta.1
- Transitive dependencies → 10.0.3:
  - `System.Text.Json`
  - `System.Numerics.Tensors`
  - `Microsoft.Extensions.Logging.Abstractions`
  - `Microsoft.Bcl.AsyncInterfaces`
  - `System.Threading.Channels`

**OpenAI 2.8.0 Breaking Changes Fixed (~23 files):**
- `OpenAIResponseClient` → `ResponsesClient`
- `ResponseCreationOptions` → `CreateResponseOptions`
- `OpenAIResponse` → `ResponseResult`
- `GetOpenAIResponseClient()` → `GetResponsesClient()`
- API: Input items now passed via `CreateResponseOptions.InputItems`
instead of separate parameter
- API: `StreamingEnabled = true` required for streaming calls
- `OpenAIResponsesModelFactory` removed → using public constructors in
tests

**ChatOptions.Reasoning Mapping:**
- Added `reasoning_effort` → `ChatOptions.Reasoning.Effort` mapping in
`PromptExecutionSettingsExtensions.ToChatOptions`, supporting `low`,
`medium`, `high`, and `xhigh` (→ ExtraHigh) effort levels per OpenAI API
documentation
- Replaced `RawRepresentationFactory` with `ChatOptions.Reasoning` in
the OpenAI and AzureOpenAI Step02_ReasoningModel sample files
- Updated migration documentation in
`.github/upgrades/prompts/SemanticKernelToAgentFramework.md` to use
`TruncationMode` as the provider-specific options example (since
reasoning now has a direct `ChatOptions` equivalent)
