arch/x86,lib: make cbmem console work in postcar stage
Implement postcar stage cbmem console support. The postcar stage is more like ramstage in that RAM is already up. Therefore, in order to make the cbmem console reinit flow work one needs the cbmem init hook infrastructure in place and the cbmem recovery called. This call is added to x86/postcar.c to achieve that. Additionally, one needs to provide postcar stage cbmem init hook callbacks for the cbmem console library to use. A few other places need to become postcar stage aware so that the code paths are taken. Lastly, since postcar is backed by ram indicate that to the cbmem backing store.
