deps: V8: cherry-pick ee2873a6303d

Original commit message:

    Fix GCC Build

    Move explicit specializations of Utf8::IsAsciiOneByteString to namespace scope

    C++ forbids explicit template specializations inside class scope.
    The specializations for IsAsciiOneByteString<uint8_t> and
    IsAsciiOneByteString<uint16_t> were defined inside class unibrow::Utf8,
    riggering "explicit specialization in non-namespace scope"
    compile errors.

    Fix type mismatch in EXPECT_EQ comparisons for std::pair values

    The tests failed because EXPECT_EQ was comparing pairs with mismatched
    template parameters — std::pair<int, unsigned int> vs.
    std::pair<unsigned int, unsigned char> — which have no valid operator==.
    I corrected the expected values to use the same unsigned types as the
    actual data, ensuring the pair comparison compiles cleanly.

    Fix build failure on GCC 12 by replacing std::format with ostringstream

    GCC 12's libstdc++ does not implement <format>, causing compile errors when
    using std::format. Replaced all std::format calls with equivalent
