feat(ios): Share with anchor (#35008)

Summary:
[`Share`](https://reactnative.dev/docs/share) currently does not support the `anchor` option in iOS, so share sheets will always be displayed in the middle of the screen on iPads and on the top left corner of the window on Mac Catalyst.

This PR utilizes the `anchor` functionality already implemented in [`ActionSheetIOS`](https://reactnative.dev/docs/actionsheetios) to bring this support to `Share` on iOS.

## Changelog

[iOS] [Changed] - type definition for the `options` parameter of `Share.share` (added optional `anchor` property)

[iOS] [Added] - `anchor` option support for `Share`

Pull Request resolved: #35008

Test Plan:
Tested with modified `rn-tester` that utilizes the `anchor` option on iPad simulator. Marked all 3 changes in code.

        setShared(null);
