NativeAOT publish fails when AsyncHelpers.RestoreInlinedFrameContexts is missing

[matouskozak]

Description

MAUI Android NativeAOT publishing fails consistently because ILCompiler expects System.Runtime.CompilerServices.AsyncHelpers.RestoreInlinedFrameContexts, but the method is absent from the supplied System.Private.CoreLib.

The failure reproduces on both Pixel8 and GalaxyA16 legs in two consecutive dotnet/performance CI builds.

Error

ILCompiler.CodeGenerationFailedException: Code generation failed for method
'Async variant: [System.Private.CoreLib]System.IO.FileStream.DisposeAsync()'

System.InvalidOperationException: Expected method 'RestoreInlinedFrameContexts' not found on type
'[System.Private.CoreLib]System.Runtime.CompilerServices.AsyncHelpers'

The subsequent dotnet publish command exits with code 1 for net11.0-android, android-arm64, with:

/p:UseMonoRuntime=false
/p:PublishAot=true
