Bring back ASInitializeFrameworkMainThread so we don't break the API (T…

…extureGroup#2050)

In PR 2032 we added alloc/dealloc texture initialization methods for the case where texture is automatically initializing. However, in doing so we have removed the `ASInitializeFrameworkMainThread` method that clients may already be using.

This PR brings back the `ASInitializeFrameworkMainThread` to live side by side with `ASInitializeFrameworkMainThreadOnConstructor` and `ASInitializeFrameworkMainThreadOnDestructor`. This should keep the old functionality in place for any client using `ASInitializeFrameworkMainThread` directly.
