docs(shared_stack): Fix incorrect or misleading expressions (IDFGH-16521)

[Narukara]

Description

From #17639

• The word "deferred" is not used to avoid being misleading.
• Clarify the purpose of mutex.
• The pointer passed to esp_execute_shared_stack_function does not point to the top of the stack, but to the starting (lowest) address of the stack.

In the Chinese version:

• 和上面的英文版一致的修改
• “调用该函数的任何函数”（caller）改为 “该函数调用的任何函数”（callee）
• 其他翻译优化
