Implement macaw-riscv-symbolic

This adds the necessary plumbing to simulate Macaw-lifted RISC-V binaries using
`macaw-symbolic`. This proves relatively straightforward, given that RISC-V
does not have a lot of special primitive functions or statements to deal with.
I have also added a basic test suite to ensure that `macaw-riscv-symbolic`
works on end-to-end examples.

Fixes #409.
