fix: accept newline type arguments without opening bracket

[jeengbe]

Currently, generic type arguments are not highlighted correctly when < appeared at the end of a line with the type identifier on the next line:

fn<
  A>();

The current possiblyMultilineTypeArgument only matches opening brackets, but not an identifier on the following line.

That fix alone caused a regression in clauses such as:

extends Type<
  A
>

(due to expressionWithoutIdentifiers>function-call now accepting it), so the short-circuit above prevents that.

Fixes #876
Fixes #1014
