feat: Add TooltipContext to set global timeout values

[frankieyan]

Short description

Back in https://github.com/Doist/reactist/pull/845, I exposed Ariakit's showTimeout and hideTimeout props to Tooltip to allow for customization, but it wasn't until I went to integrate it did I realize my mistake - we don't want to have to set this on every single tooltip instance 🥲 So we are adding a provider in order to be able to define these values just once in the app.
