[New VM] Make a single “env_info” function to extract information from the host

Make a single “env_info” function to extract information from the host, i.e. blocktime, caller, transferred_value, block hash, etc. Needs to have feature parity with 2.0 impl. Currently, there is a separate host function per item.

Start by locating the New VM host functions and comparing them with the 2.0 implementation. Identify the separate functions for blocktime, caller, transferred value, block hash, and other host data; done means one env_info function provides feature parity with 2.0.
