bug#71959: [PATCH] Improve `tab-line-tabs-fixed-window-buffers` sorting performance

[Eval Exec]

Enhanced
`tab-line-tabs-fixed-window-buffers` performance by optimizing buffer
sorting mechanism. Replaced inefficient `seq-position` calls with a hash
table to cache buffer positions, significantly improving speed when
handling large buffer lists.
