    [vs17.2] Temporary turn off static graph restore. (#8697)

    Turn off static graph restore.

    (Backport of #8498 to vs17.2)

commit 872ddd9
Merge: 94fcedf 6faa1d5

    Merge pull request #8419 from Forgind/fix-temp-file-filtering-17.2

    Fixes AB#1678521

    Context
    #8049 broke the temp filtering logic by using the MSBuild-specific temp path instead of the true base temp path. This manifests as an overbuild of some C++ projects.

    Changes Made
    Reverted the change. Enabled relevant unit tests.

    Testing
    Existing unit tests and a C++ end-to-end repro.

    Notes
    The rest of FileTracker tests cannot be enabled without significant work (related to #649).
