    Update Supported Windows SDK to 10.0.26100.4654

    This updates the windows toolchain package used to build chromium to
    the newest version. This is a minor version bump, so it's pretty smooth:
    no compilation failures, and few places that need to be updated. There
    were no changes to mc or idl output.

    This SDK version undoes the problematic linking of d3dcompiler_47.dll
    (crbug.com/372059340), so the packaging process is simpler and we are
    now using the most recent version of that dll.

    -----------------------------------------------------------------
    Instructions to reproduce:

    These instructions are best done on a fresh VM. Make sure to uninstall any existing installations of Visual Studio and any existing SDK installations before starting.

    1. Install git for windows from their website, with the default settings (https://git-scm.com/downloads/win)
    2. Install depot_tools following the instructions on their webpage (https://commondatastorage.googleapis.com/chrome-infra-docs/flat/depot_tools/docs/html/depot_tools_tutorial.html#_setting_up)
    3. Download Visual Studio Professional (Free Trial) from the official site (https://visualstudio.microsoft.com/downloads/)
    4. Run the VS installer with the following arguments:
    ```
    $ VisualStudioSetup.exe --add Microsoft.VisualStudio.Workload.NativeDesktop --add Microsoft.VisualStudio.Component.VC.ATLMFC --add Microsoft.VisualStudio.Component.VC.Tools.ARM64 --add Microsoft.VisualStudio.Component.VC.MFC.ARM64 --includeRecommended --passive
    ```
    5. Open the VS installer (from the start menu), click “Modify”, and uninstall any existing SDK versions (search for “windows sdk”).
    6. Open “Add or Remove Programs” and make sure there are no SDK versions installed; remove them if so (search for “windows software development kit”).
    7. Download SDK Version 10.0.26100.4654 from the official site (https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/). Note that if a more recent version has been released, it may no longer be available.
    8. Run the SDK installer with default settings, except disable “insights”.
    9. Run the packaging script from depot_tools, e.g
    $ vpython3 depot_tools\win_toolchain\package_from_installed.py 2022 -w 10.0.26100.0

    Link to packaging script version used for packaging: https://source.chromium.org/chromium/chromium/tools/depot_tools/+/main:win_toolchain/package_from_installed.py;drc=1867bb56c124ea7e6d8cdc023244b31a2c41bf1f

    This resulted in the final package with hash e4305f407e.
