Subject: [PATCH] xdg-activation: Deduplicate token creation code

There were three places initializing a token:

- wlr_xdg_activation_v1_add_token
- wlr_xdg_activation_token_v1_create
- activation_handle_get_activation_token

The initialization of the token.destroy was missing in the first one. To
prevent these functions from getting out of sync move the token creation
into a common function.

Fixes 4c59f7d4 ("xdg-activation: Allow to submit tokens")
