runtime(vim): Update base-syntax, improve :map highlighting (https://github.com/vim/vim/issues/14141)

Improve :map command highlighting.

- Fix multiline RHS matching, allow continued lines and comments.
- Allow ^V-escaped whitespace in LHS.
- Handle map-bar properly and allow trailing commands.

Fixes issue #12672.
