AK: Make debugging URLParser easier

This patch adds a state_name method to URLParser to convert a state to a
string. With this, the debugging statements now display the state names.

Furthermore, this fixes a bug where non-ASCII code points were
formatted as characters, which fails an assertion in the formatting
system.
