roll: pigweed pw_allocator: Add conversions for managed pointers
This CL adds additional ways to convert managed pointers of one type to
another, in order to make them more flexible and usable by downstream
projects.
* Explicit conversion operators are added to allow downcasting.
* A SharedPtr constructor that takes a UniquePtr is added.
* Some missing comparison operators were added to aid testing.
