Removed Into<AssedId<T>> for Handle<T> as mentioned in #12600 (#12655)

Fixes #12600 

## Solution

Removed Into<AssetId<T>> for Handle<T> as proposed in Issue
conversation, fixed dependent code

## Migration guide

If you use passing Handle by value as AssetId, you should pass reference
or call .id() method on it
Before (0.13):
`assets.insert(handle, value);`
After (0.14):
`assets.insert(&handle, value);`
or
`assets.insert(handle.id(), value);`
