Use hash based IDs for type instead of a pointer to static data

[gracicot]

Is your feature request related to a problem? Please describe.
For type id, we use the address of a static variable. This is a problem. For instance, this can create problems in DLLs (#80) and some compiler can optimize them with the default settings for production build (#96).

Describe the solution you'd like
We should generate a unique hash for each type that is reproducible and stable between compilers and platform. This is possible and proven by TheLartians/StaticTypeInfo

The __PRETTY_FUNCTION__ variable cannot be used in constexpr contexton GCC older than version 8. We want to ship but don't want to break so it will be available as an option in the CMake setup.

Fixed in dev-4.3.x. It can be enabled by passing -DKANGARU_HASH_TYPE_ID=ON on the CMake command line
