Try disabling AV in the official build script to avoid build breaks that manifest as ``` D:\a\_work\1\s\.packages\microsoft.dotnet.arcade.sdk\9.0.0-beta.24516.2\tools\Sign.proj(72,5): error MSB4018: The "Microsoft.DotNet.SignTool.SignToolTask" task failed unexpectedly.

Context
Fixes #11394
This is a regression. The bug appeared after Expand MSBuildSdkResolver.
Customer impact
Without this fix the customers that opt-into
MsBuildUseSimpleProjectRootElementCacheConcurrencywill getSystem.NotImplementedException. This includesslngenandquickbuild.Details
The
NotImplementedExceptionis thrown here:msbuild/src/Build/Evaluation/SimpleProjectRootElementCache.cs
Lines 133 to 136 in aff5455
Previously the
SdkResultofMSBuildSdkResolverwas empty andProjectRootElementwas never created for it. Now, it contains 2 properties, and whenProjectRootElementis created, every change marks it as dirty. The fix is not to mark it dirty when it is fromSdkResultChanges made
Implemented internal
CreateNotDirtythat createsProjectRootElementthat cannot be dirtied.Testing
Added unit test for
CreateNotDirty. Also manually tested that the exception is not thrown anymore.Risks
Low - existing tests ensure that other scenarios are not broken, added new test, also tested manually this exact case.
