[Feature] add a `cargo-risczero info` command to dump version info of components

[Erik Kaneda]

Feature

A cargo-risczero info command will dump information regarding client/server version, rust toolchain version and c toolchain version.

Motivation

Right now, we can get the version of the risc0 rust toolchain by running cargo +risc0 --version and we can dump the client server info by doing cargo risczero --version. It would be nice to have one command display version info for all components.

Implementation

In cargo-risczero utility, add a command to dump the version of itself, the linked risc0 rust tool chain and (in the near future) the c toolchain.
