frame-parameter buffer-list is being overwritten too early on Emacs 31

[shipmints]

Emacs 31 is coming with a tab-bar change (that I wrote! that interferes with bufferlo). tab-bar-tab-post-open-functions are now called when tab-bar-tabs-function bound to tab-bar-tabs is called on a new frame. It was an oversight that the first tab created never got the callback and that was rectified.

tab-bar-tab-post-open-functions are called before after-make-frame-functions and the selected frame during that initial call is not the new frame, but the old frame. bufferlo--tab-include-exclude-buffers assumes the selected frame is the correct one and calls bufferlo--include-exclude-buffers with a nil argument and that interferes with the originating tab's buffer-list.

I've tested a solution which relies on hooking into before-make-frame-hook to inhibit bufferlo--tab-include-exclude-buffers and rely on bufferlo--include-exclude-buffers which gets called right afterward anyway by after-make-frame-functions. The inhibition is lifted by bufferlo--include-exclude-buffers. The variable can't be let-bound unless we advice make-frame which I'd rather not do. It seems to avoid the issue. I will submit a PR.
