zephyr: Add basic support for shared memory
On the EC, shared memory is at the top of RAM, above all linker symbols
that are located in RAM.
Add a simple shim for this. At present it does enough to compile, but
does not actually work. Yuval probably knows what should be done here.
Add a Kconfig for the 'shmem' command.
