Added special handling for SDL_HINT_ANDROID_ALLOW_RECREATE_ACTIVITY

Browse Source 
This hint needs to persist outside of the normal application flow, so use the environment to set the initial value, and then save the value set via SDL_SetHint() after that.

Fixes https://github.com/libsdl-org/SDL/issues/12677

(cherry picked from commit 6bb16296b0)
