runtime(doc): Improve :help builtin-function-list table formatting

Commit: https://github.com/vim/vim/commit/3913f13a7d87885e3970c1f7529ddce1a9ffa967

runtime(doc): Improve :help builtin-function-list table formatting

- Start each field at the correct tabstop - on a new line if required.
- Use "Type1/Type2" for return types rather than "Type1 or Type2",
matching the dominant style.
- Convert hyperlinked Ex commands to command markup, `:cmd`.
- Wrap overlong lines.

closes: #18438
