String escape character sequence update

Single-quoted strings in meson have been taught the same set of escape sequences as in Python. It is therefore now possible to use arbitrary bytes in strings, like for example NUL (\0) and other ASCII control characters. See the chapter about Strings in Syntax for more details.

Potential backwards compatibility issue: Any valid escape sequence according to the new rules will be interpreted as an escape sequence instead of the literal characters. Previously only the following escape sequences were supported in single-quote strings: \', \\ and \n.

Note that the behaviour of triple-quoted (multiline) strings has not changed. They behave like raw strings and do not support any escape sequences.
