vim9script Port of vim-unimpaired

- Expose most of the functions used for map building through autoload so
  that others can more easily add maps in the same manner without
  copying code.

- Incorporate tpope#230, tpope#228

- Use <ScriptCmd> instead of `:<C-U>`, which required some rethinking
  because of the use of `<C-R>=`.

- Added additional maps from
  - phongnh/vim-toggler: conceallevel, showmatch, incsearch, expandtab,
    showcmd
  - riceissa/vim-more-toggling: syntax

-There are mappings which are simply short normal mode aliases for
-commonly used ex commands. `]q` is :cnext. `[q` is :cprevious. `]a` is
-:next.  `[b` is :bprevious.  See the documentation for the full set of

-There are linewise mappings. `[<Space>` and `]<Space>` add newlines
-before and after the cursor line. `[e` and `]e` exchange the current
-line with the one above or below it.

 There are mappings for toggling options. `[os`, `]os`, and `yos` perform
-`:set spell`, `:set nospell`, and `:set invspell`, respectively.  There's also
-`l` (`list`), `n` (`number`), `w` (`wrap`), `x` (`cursorline cursorcolumn`),
-and several others, plus mappings to help alleviate the `set paste` dance.

-There are mappings for encoding and decoding. `[x` and `]x` encode and
-decode XML (and HTML). `[u` and `]u` encode and decode URLs. `[y` and
-`]y` do C String style escaping.
