Philippe Crama 721f167563 (perf)utils: optimize org-roam-plist-map! (#1958) ...

The old implementation:

- did not handle duplicate keys well (the function would be applied to each value, but only the first value would be updated with the last value's result)
- was quadratic in the length of the input list (for each key, plist-put would search for the first occurrence of the key by going through all previous elements again)
- copied the input sequence even though this was not really needed
- did not provide a result value that could be useful, thus encouraging imperative programming
- did not need to be a macro, and the macro implementation was evaluating fn multiple times and causing warnings in the native compiler because k and v were not bound.
