Add an option so that opening a file from macOS’s "external editor" mechanism does not bring macvim to foreground

In macOS, I am setting the default editor for source code files to open with macvim be default so that macvim can be the editor when debugging on lldb with lldb --editor. However, whenever a breakpoint is hit, or a frame changed, the focus automatically goes from lldb to macvim. I wish I could keep the focus on lldb instead.

Describe the solution you'd like

Maybe there could be an option called macvim_dont_bring_to_foreground, set to 0 by default, that enables the current behavior (bringing macvim to foreground when a remote command arrives), and can be set to 1 to disable the foreward bringing).

Describe alternatives you've considered

I have considered using vim in the terminal instead, by the server part of +clientserver is disabled.

EDIT: lldb don’t use $EDITOR but the host’s external editor instead.

首先跟踪 MacVim 对 macOS external-editor 或 remote-command 的处理，以及 breakpoint 或 frame 发生变化时激活应用程序的位置。完成的标准是：可配置选项默认保留当前的前台行为，同时允许打开远程文件时让 lldb 保持焦点；通过 external-editor 工作流验证这一点。
