Adjust the tooltip performance (see #7687)

Description
-----------

Fixes #7685

PR aims to change how the tooltip controller works

1. Only observing tooltip changes
2. Using Set instead of an array for faster access (Unsure if we could use WeakSet due to garbage collection)

/cc @m-vo can be tested on the current `5.x` with https://github.com/zoglo/contao/tree/fix/stimulus-tooltip
