Preview of Xcode 27 support

This release include preview support for Xcode 27.

To build with support for Xcode 27 and any new API bindings we've implemented so far, append 27.0 to the target framework in the project file. Additionally, ignore a warning about using the Xcode 27.0 preview. Note: .NET 10 must be used, we don't have .NET 11 builds with Xcode 27 support yet.

Example:

<PropertyGroup>
  <TargetFramework>net10.0-ios27.0</TargetFramework>
  <NoWarn>$(NoWarn);XCODE_27_0_PREVIEW</NoWarn>
</PropertyGroup>

This requires installing Xcode 27.0 beta 6.

See .NET 10 - Xcode 27.0 Beta 6 support for the release notes for the support for Xcode 27.
