```
Escape control characters in syntax tree view (#59012)

Escaping control characters so they correctly render in the syntax tree.
Note: the original issue debates whether "\n" should be printed at all.
It should if it's part of the grammar syntax. In the example posted
below, "\n" is printed because it's part of the c-preprocessor grammar,
but "\t" which is not, is not printed.
Note2: I've added an inline test since I saw that only bigger,
integration tests get their own file. Feel free to give guidance on the
topic.
