[Optimize] doom-modeline-buffer-file-name for all truncate styles.
e.g.`truncate-upto-project' is ~5x faster.
(benchmark-run 1000 (format-mode-line mode-line-format))
~0.7s vs ~4s
Also add 2 new styles: `truncate-from-project' and `truncate-except-project'.
Given ~/Projects/FOSS/emacs/lisp/comint.el
truncate-upto-project => ~/P/F/emacs/lisp/comint.el
truncate-from-project => ~/Projects/FOSS/emacs/l/comint.el
truncate-with-project => emacs/l/comint.el
truncate-except-project => ~/P/F/emacs/l/comint.el
NOTE: `shrink-path-file-mixed' has so BAD performance! Damn it!!!
