macros: Allow parsing :tt fragments
:tt fragments stand for token trees, and are composed of either a token,
or a delimited token tree, which is a token tree surrounded by
delimiters (parentheses, curly brackets or square brackets).
This should allow us to handle a lot more macros, including extremely
powerful macro patterns such as TT munchers
