Steering the memory policy locally at the level of methods and functions is redundant, because one can always define pythonizations that take care of that. Removing this feature allows us to add new policy flags without increasing the net complexity of the library. With this feature removed, one single bool flag to indicate the heuristic memory policy is enough, because there is no need to use 4 bits to encode the combination of local and global policies anymore.
In ROOT, we need to disable this for type safety and overload resolution reasons.

Remove the local memory policy attribute feature, because
1 ) cppyy uses by default the strict memory policy anyway
2 ) ROOT doesn't need it
3) the same result can be achieved with pythonizations
4) simplifying code is good
On the other hand, introduce a new policy to control the implicit conversion to smart pointer arguments, which we would like to not to have in ROOT. So far, I just patched it out in ROOT, but to avoid a patch, it would be better to be able to change this via static flags.
Corresponds to:
