Support for custom anchor position in popover

[divyam234]

Provide a general summary of the feature here

React aria popover doesn't support custom anchor position(top and left postion) if given explicitly it only works with trigger elements it should also support random placement which will help in implementing context menus currently there is no way to react aria to achieve this.

🤔 Expected Behavior?

NA

😯 Current Behavior

NA

💁 Possible Solution

Maybe

react-spectrum/packages/@react-aria/overlays/src/useOverlayPosition.ts

Line 152 in 81e672f

let position = calculatePosition({

there should be option here to use anchor position by given by user instead of calculating through trigger element

🔦 Context

Helps in implmenting right-click context menu

💻 Examples

In material-ui popover has props like

anchorPosition:{top:number,left:number}
anchorReference="anchorPosition"

which will place itself wrt to anchor position

This sounds reasonable to me, will need to double check how our overlay hooks behave without an explicit trigger element though, may need to some enhancements to ensure focus management goes somewhere meaningful in that case.

@LFDanLu Currently I'm using floating ui with rac for implementing context menus it's working fine didn't encounter any focus related issues with rac overlay component but I would be nice if rac provides extra prop for this.
