[Feature]: Exposing focus scope stack

[nicooprat]

Describe the feature

We're in the process of migrating to Radix, but we're already using this package to handle focus traps: https://github.com/focus-trap/focus-trap

We need to use stacks, for instance when trying to close a modal and displaying an alert to prevent losing modifications: the focus must be trapped in the alert, then in the dialog once dismissed.

Currently we can't migrate only one or another because the focus scope API in Radix is not exposed: https://github.com/unovue/radix-vue/blob/v2/packages/core/src/FocusScope/stack.ts

Could we imagine a solution so the two packages are compatible in order to ease a migration process?

Thanks
