Only inherit the handles that are really needed.

Currently all handles are inherited to child processes. For more information see https://discord.com/channels/400588936151433218/687365466422902841/1072485165491814430

I would really like to see an RAII type for this.

Only for the clean up or for everything? So should a failure in the constructor (calls InitializeProcThreadAttributeList) throw an exception?

[BillyONeal]

I wish it were for the pipes too but that's preexisting so won't ask you to go there. I meant something like:

struct ProcAttributeList {
    static ExpectedL<ProcAttributeList> create(DWORD dwAttributeCount);
    ExpectedL<Unit> update_attribute(DWORD_PTR Attribute, PVOID lpValue, SIZE_T cbSize);
    ~ProcAttributeList();
    LPPROC_THREAD_ATTRIBUTE_LIST get() const noexcept { return reinterpret_cast<LPPROC_THREAD_ATTRIBUTE_LIST>(buffer.data()); }

    ProcAttributeList(const ProcAttributeList&) = delete;
    ProcAttributeList& operator=(const ProcAttributeList&) = delete;
private:
    ProcAttributeList(/* *** */);
    std::vector<unsigned char> buffer;
};

Have done this in a3bbb30

Thanks for the fix!
