`react-aria-components/Tooltip`: `state.placement` should receive full `Placement` instead of `PlacementAxis`

[unional]

Provide a general summary of the feature here

Currently the state.placement in className or style callback is a PlacementAxis, which only contains top | bottom | left | right.

When the position of the tooltip needs to adjust, it may also need to flip.

e.g. a button at the top-left corner with a tooltip placement='top end' should flip on both axis to bottom start.

Currently we only get bottom which does not provide enough information to adjust the css accordingly.

🤔 Expected Behavior?

state.placement contain full Placement information.

😯 Current Behavior

state.placement only contains PlacementAxis values.

By the way, do you know in what case state.placement will contain the value center?
