[dotnet] Add DeployToDevice MSBuild target for 'dotnet run' support

[rolfbjarne]

---

⚠️ Note to self: needs testing locally ⚠️

---

Implement the DeployToDevice target as specified in the dotnet run for MAUI spec. This target deploys an already-built app to a device or simulator without rebuilding, enabling the dotnet run --no-build workflow.

The target:

• Reuses existing GetMlaunchArguments task to compute install arguments
• Supports both physical devices (--installdev) and simulators (--installsim)
• Accepts the $(Device) property for device selection
• Depends on ComputeAvailableDevices for device discovery
• Only applies to mobile platforms (iOS/tvOS) via SdkIsMobile condition

Fixes #24382
