`_PyStaticCode_InternStrings` is called ~800 times during startup.

The _Py_Deepfreeze_Init() function calls _PyStaticCode_InternStrings once for each string.

Creating the interned string dict in one go, from the table of static strings would be much faster.
something like this (error checking omitted, and other liberties taken for brevity)

_Py_CreateInternedDict(PyObject **strs, int n) {
   PyDictKeys *table = make_dict_keys(n);
   for (int i = 0; i < n; i++) {
        table->entries[i].key = table->entries[i].value = strs[i];
        table->entries[i].hashcode = strs[i].hash_code;
        // Fix up size and entries here.
   }
   return new_dict(table);
}

All the hash codes will need to be initialized first, but we probably should do that anyway.

首先跟踪 _Py_Deepfreeze_Init() 及其对 _PyStaticCode_InternStrings 的调用。检查 interned string dictionary 和字符串哈希码是如何初始化的，然后确定所提议的批量构建是否保留了所需的字典状态和启动行为。
