Merged PR 54952: Getting ready for the 10.0 stable release. Flowing .NET Servicing

#### AI description  (iteration 1)
#### PR Classification
This PR updates dependency versions and build pipeline configurations to prepare for the .NET 10.0 stable release.

#### PR Summary
The changes update dependency and LTS versions (upgrading many from 9.0.10 to 9.0.11), enable release-specific flags, and streamline the build pipelines for servicing.
- **`eng/Version.Details.xml` and `eng/Versions.props`**: Upgraded various dependency versions and LTS numbers and set stabilization flags (e.g., `StabilizePackageVersion` to true, `DotNetFinalVersionKind` to release).
- **`azure-pipelines.yml`**: Removed the code coverage stage to simplify the CI pipeline.
- **`eng/pipelines/templates/BuildAndTest.yml`**: Added tasks to set up private feed credentials and commented out integration tests that require authentication.
- **`NuGet.config`**: Revised package source configuration by removing package source mapping and adding new internal feed URLs.
- **`Directory.Build.props`**: Suppressed NU1507 warnings to accommodate internal branch configuration.
