How 'bout always defining `treesit-parser-list` (and making it return
`nil` if Emacs was compiled without Tree-sitter support)?

Most places that can make use of Tree-sitter probably would probably
prefer not to have to worry about the subtle distinction between
"Tree-sitter support is available but not for this major mode" and
"Tree-sitter support is not available at all".
