Remove ngen uninstall workarounds

[MichaelSimons]

Within the SDK images there are several ngen uninstall calls to remove assemblies that have been queued to be ngen'd but fail to ngen. In order to remove the workarounds, VS will need to address their issues first.

Example:

RUN `
    # Workaround for issue with 32 bit assemblies from .NET Framework 4.8 SDK being 64 bit ngen'ed
    \Windows\Microsoft.NET\Framework64\v4.0.30319\ngen uninstall "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\SecAnnotate.exe" `
    && \Windows\Microsoft.NET\Framework64\v4.0.30319\ngen uninstall "C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.8 Tools\WinMDExp.exe" `
    `
    && \Windows\Microsoft.NET\Framework64\v4.0.30319\ngen update `
    `
    # Workaround VS installer/ngen issues
    && \Windows\Microsoft.NET\Framework\v4.0.30319\ngen uninstall "C:\Program Files (x86)\Microsoft Visual Studio\2019\TestAgent\Common7\IDE\VSWebLauncher.exe" `
    && \Windows\Microsoft.NET\Framework\v4.0.30319\ngen uninstall "C:\Program Files (x86)\Microsoft Visual Studio\2019\TestAgent\Common7\IDE\CommonExtensions\Microsoft\Editor\Microsoft.VisualStudio.Diff.CommandLineSwitch.pkgdef" `
    && \Windows\Microsoft.NET\Framework\v4.0.30319\ngen uninstall "C:\Program Files (x86)\Microsoft Visual Studio\2019\TestAgent\Common7\IDE\CommonExtensions\Microsoft\Editor\Microsoft.VisualStudio.Diff.pkgdef" `
    `
    && \Windows\Microsoft.NET\Framework\v4.0.30319\ngen update

@mthalman, We should take inventory of the remaining uninstalls and ensure there are active product issues to address the underlying problems.

The following files are uninstalled from the ngen queue to workaround issues:

• Microsoft.Tpm.Commands.dll (bug link [MSFT internal])
• SecAnnotate.exe (bug link [MSFT internal])
• WinMDExp.exe (bug link [MSFT internal])
• VSWebLauncher.exe (bug link [MSFT internal])
• Various Roslyn files (A bunch of files in the Roslyn folder are mistakenly queued for ngen dotnet/roslyn#38296)
• Microsoft.VisualC (bug link [MSFT internal])
