0033606: speedup Preferences.getAllPreferences by improving getPreferenceFromList functions to do early return

DescriptionThat function does a manually coded complicate list search.

However most entries in that list will be for different properties and not just different in visibility.

So doing early check & return of the properties part in the comparison can save some cpu cycles.

On testing with bigger db that shaves of 50-60ms of all runtime on getAllPreferences.

From around 120ms (of the loop in getAllPreferences) downto 60ms

Note using a Map here instead of list with a key matching the open coded list search could give another speedup

Fixed issue 33606: The Preferences.getPreferenceFromList improved.

A continue has been added to do an early return in a for loop of the Preferences.getPreferenceFromList method. Putting this code there prevents a lot of executions needed to get the "winVisibilityNotDefined" and the "sameWinVisibility" variables.
The "isCurrentPreference" variable needs to be true to make this piece of code true: "if (isCurrentPreference && (winVisbilityNotDefined || sameWinVisibility)) {" and to return the listPref value. So, if the "isCurrentPreference" is false, it doesn't matter the values of the "winVisibilityNotDefined" nor "sameWinVisibility" values. That is why is a good idea to put the early return. In this way a lot of executions to get the variables will be avoided.
