1. add support for remapped and aliased modes …

   This patch tries to make `bind-map` aware of two ways in which major modes can
   be remapped: via aliasing or via `major-mode-remap-alist`.
   
   The motivating scenario is AUCTeX, which as of version 14.0.1 has renamed
   several major modes, e.g., latex-mode has been renamed as LaTeX-mode. AUCTeX
   attempts to offer backwards compatibility using a mix of remapping and aliasing.
   For users of emacs < 29, `latex-mode` is redefined as an alias for `LaTeX-mode`,
   whereas for users of emacs 29+, `latex-mode` is remapped to `LaTeX-mode` using
   `major-mode-remap-alist`.
   
   However, if a user had configured keymaps for `latex-mode` using `bind-map`,
   they will not be available in `LaTeX-mode`. This is especially problematic for
   distributions like `spacemacs` which need to support users of both old and new
   AUCTeX (see syl20bnr/spacemacs#16282 for more discussion).
   
   This patch introduces two new customizable options,
   `bind-map-use-remapped-modes` and `bind-map-use-aliased-modes`. Both options
   default to `t`, in which case when `bind-map` is deciding whether to activate a
   given keymap, it will compare the value of `major-mode` to not only the symbol
   for which the keymap was configured configured (e.g., `latex-mode`), but any
   remapped or aliased modes (e.g., `'(latex-mode LaTeX-mode)`. This logic is
   implemented in the new (private) function `bind-map--lookup-major-modes` to
   facilitate lookup of applicable major-modes on the fly. As a result, if a user
   adjusts `major-mode-remap-alist` or adjusts aliased, `bind-map`'s behavior will
   change accordingly.
