  [lldb] Avoid unnecessary regex check in dwim-print (#114608)

An (unmeasured) improvement to performance of `dwim-print` when used as `po`.

This change lifts the check for `note_shown` to the top of the lambda, to avoid all subsequent work when the hint has already been shown. The main effect is to avoid performing a regex match when the hint is not going to be shown.

This change also constructs the `std::regex` only once, by making it static.
