Subject: [PATCH] vim-patch:211211052d04 (#27048)

runtime(odin): include ftplugin, syntax and indent script (vim/vim#13867)

https://github.com/vim/vim/commit/211211052d0426394cbd5f42f3f3f78a64822e2a

Translate the files from Vim9 script to legacy Vim script. Notably:

- Prefer case-matching comparisons where needed.
- Save and restore `&cpo`.
- Make the functions script-local. (Pretty easy to use these in expr options now
  since Vim 9.0 anyways)

Add a note after the header for each file stating that they're manually
translated.
