Add tooltips to effect property controls

Add an option for developers to add tooltip text help to effect property controls.

This would help with discoverability of features, as well as reducing confusion when returning to an infrequently used effect, for example in a old project or a received projects.

It would be particularly useful for new users to learn AE, or when dealing with a new plugin and the property labels might not be able to fully convey what effect that control will actually have.

A global preference to turn tooltips on or off would be useful too, for users who do not want to see them. Perhaps a tooltip activation time could be set by the user too, so that a longer hover would be required to avoid them appearing too frequently for experienced users.

Another option might be for tooltips to display in the Effects Panel, Timeline, or both. Some users might prefer to only have them show in the Effects Panel for example, but not want the extra visual density in the timeline.

A next-level bonus would be to have the tooltips be able to link directly to a help page for that specific feature - not dissimilarly to how Cinema help works by opening the relevant help page (usually 😂), or the ‘i’ icon in Plasticity that takes the user directly to the web page for the selected tool.

But the core request would be to have tooltips that can be added per-property by developers to aid discoverability and improve the user experience.
