Currently clang-format uses ContinuationIndent to indent the contents of a raw
string literal that is the last parameter of the function call. This is to
achieve formatting similar to trailing:

  f(1, 2, R"pb(
      x: y)pb");

However this had the unfortunate consequence of producing format like this:

  fffffff(1, 2,
          R"pb(
      a: b
          )pb");

This patch makes clang-format consider indenting a trailing raw string param
after a newline based off the start of the format delimiter, producing:

  fffffff(1, 2,
          R"pb(
            a: b
          )pb");
