Implent try_from_debug_info_mut

[ksew1]

When we implement a function with the following signature:
fn try_from_debug_info_mut(sierra_debug_info: &mut DebugInfo) -> Result<Self, Self::Error>;
we could remove elements from the underlying hashmap and take ownership of them when deserialized, thus eliminating the need for cloning.

However, this would result in the function no longer being idempotent.
