  [Demangle] demangle builtin type transformations

Fixed: https://github.com/llvm/llvm-project/issues/62127
https://reviews.llvm.org/D116203 introduced several compiler builtin
equivalents of the unary type traits. In some cases (e.g. template) those
builtin will be dependent and need to be mangle.
This patch add the check for `u{builtin}I{type}E` to demangle it.
