deps: V8: cherry-pick b161a0823165

Original commit message:

    [msvc] implement symbols without inline assembly

    MSVC does not support inline assembly (clang-cl does).

    Those two functions needs to be implemented using C++ only. Implemented
    a version for MSVC only, based on an intrinsic (that guarantees load,
    even with optimization) available for any architecture.
