Fix Android NativeAOT builds failing with PrivateSdkAssemblies error

[Copilot]

Fixes the Android NativeAOT build failure that occurs when CodegenType=NativeAOT is specified:

error : The PrivateSdkAssemblies ItemGroup is required for _ComputeAssembliesToCompileToNative

The issue was that the ".NET Android Default Template" scenario was missing the condition to exclude NativeAOT builds, while all other Android scenarios in the same project file already had this exclusion.

Android NativeAOT is experimental and not yet suitable for production use (as indicated by the warning in the build logs). The fix adds the same condition Condition="'$(CodegenType)' != 'NativeAOT'" to the netandroid scenario that was already applied to all other Android scenarios:

• MAUI Android Default Template
• MAUI Android Sample Content Template
• MAUI Blazor Android Default Template

This ensures consistent behavior across all Android scenarios and prevents the MSBuild error by excluding Android scenarios from NativeAOT builds entirely.

Fixes #4904.
