vmbase: Add CPU-specific submodules to crate::arch
Add a crate that will be used to provide CPU architecture-agnostic
functionality to which we will eventually move all the AArch64-specific
code currently present in vmbase, pvmfw, and Rialto. Submodule names
follow the rustc target_arch config.
Test: m pvmfw_bin
