Handle very large url pattern input

Reviewed by Ryosuke Niwa and Matthieu Dubet.
When creating a URLPattern with a string as an input, it is possible to
create it with a string so large that the underlying token list (vector)
will intentionally crash when performing an append operation and the
capacity cannot be increased. Check the result of each token append
operation and throw an exception if an append cannot be performed.
