deps: V8: cherry-pick de611e69ad51

Original commit message:

    [maglev] fix non-ptr-compr compilation on old compilers

    When pointer compression is disabled, the preprocessor expands some
    static asserts to static_assert(false), which doesn't compile on
    compilers not implementing the C++ defect report CWG2518, notably clang
    before version 17 and gcc before version 13.

    Adding in part of the template parameter to the static assert prevents
    it from being evaluated immediately which fixes the compilation.

    Test: compiled with gcc-11 and clang-14 without pointer compression.
