Lexical classification for template strings #1744

This PR adds lexical classification support for template strings in the absence of a syntactic classifier.

It will break in the presence of

  • Nested template strings that span multiple lines.
  • Nested expressions composed of curly braces, where the closing curly falls on the next line.

But otherwise it is a fairly good approximation.

var offset = 0;
var token = SyntaxKind.Unknown;
var lastNonTriviaToken = SyntaxKind.Unknown;
var templateStack: SyntaxKind[];
