Refactor syscall handler meta (aka. remove it completely).

[azteca1998]

The SyscallHandlerMeta was used to store the pointer to the Starknet syscall handler. We don't need it to compile the program therefore it is unnecessary. The syscall handler is now provided to the invoke_* functions directly, which solves some of the issues we have with duplicated MetadataStorages.
