The example is currently building a crosvm with gpu support, which
doesn't link properly out of the box. Now, we build explicitly with all
features off, which is sufficient to run the example.
BUG=none
TEST=ran the example.

Use an INT3 (0xCC) instruction to cause the example to exit after
printing the message. This is more convenient than having to manually
kill crosvm from another terminal.
BUG=None
TEST=Run baremetal and observe that it exits

Fix loading of the example baremetal kernel with the fixed ELF kernel
loader:
- Remove the "RAM" address space so virtual and physical address match.
- Remove the 0x200-byte padding now that entry point address is used.
BUG=b:234155022
TEST=Run baremetal as in tools/examples/baremetal/README.md

rwroot automatically adds root=/dev/vd[a-z], but the example image
actually uses /dev/vda5. This leads to confusion when two root= kernel
command line arguments are passed in and only one of them works.
Therefore we use rwdisk instead which doesn't add the kernel argument.

Two examples are added. A simple one and one with network
configured.
The examples are written in a way they can be integrated
with the mdbook to form a tutorial. This will ensure the
tutorial code snippets stay up to date.
The documentation for networking is added after
https://crrev.com/c/3237468 is merged.
