runtime(tohtml): Update TOhtml to version 9.0v2 (#13050)
Modified behavior:
- Change default value of g:html_use_input_for_pc from "fallback" to
"none". This means with default settings, only the standards-based
method to make special text unselectable is used. The old method
relying on unspecified browser behavior for <input> tags is now only
used if a user specifically enables it.
- Officially deprecate g:use_xhtml option (in favor of
g:html_use_xhtml) by issuing a warning message when used.
Bugfixes:
- Fix issue #8547: LineNr and other special highlight groups did not
get proper style rules defined when using "hi link".
- Fix that diff filler was not properly added for deleted lines at the
end of a buffer.
Other:
- Refactored function definitions from long lists of strings to use
:let-heredoc variable assignment instead.
- Corrected deprecated "." string concatenation operator to ".."
operator in more places.
