d692dfb8e3 vmm: Move impl Default for ... to vm_config.rs 
This is consistent when considering that some structs have a
`#[derive(Default)`] so it makes sense for the default implementations
to be in the same location.

7ad58457b0 vmm: Split structs from logic that make up VmConfig 
Place the data structures that are required for constructing a VmConfig
into it's own module from the logic that exists to suppot them.

This is useful as a consumer of the API can now clearly see what data
structures make up the API for creating VMs.

This has no functional change and I made no attempt to clean up the
ordering (it's as in the original file) nor any other clean up.

4fea40f008 fuzz: Balloon: Reduce the guest memory size and queue size 
With the guest memory size of 1MB, a valid descriptor size can be close
to the guest memory size (e.g. 1MB) and can contain close to 256k
valid pfn entries (each entry is 4 bytes). Multiplying the queue
size (e.g. 256), there can be close to 64 millions pfn entries to
process in a single request. This is why the oss-fuzz reported a
timeout (with a limit of 60s).

By reducing the guest memory size and the queue size, the worst-case now
is 8 million pfn entries for fuzzing, which can be finished in around 20
seconds according to my local experiment.

operations too.

Also added a `simple_api_full_command()` to avoid having to specify the
file descriptors, in a similar manner to `simple_api_command()`.

b2d1dd65f3 build: Remove "fwdebug" and "common" feature flags 
This simplifes the buld and checks with very little overhead and the
fwdebug device is I/O port device on 0x402 that can be used by edk2 as a
very simple character device.

See: #4679

ef603fde4c fuzz: Reduce the guest memory size for balloon fuzzer 
As the virt queues are initialized with random bytes from the fuzzing
engine, a descriptor buffer for the available ring can have a very large
length (e.g. up to 4GB). This means there can be up to 1 billion
entries (e.g. page frame number) for virtio-balloon to process a signal
available descriptor (given each entry is 4 bytes). This is the reason
why oss-fuzz reported a hanging issue for this fuzzer, where the
generated descriptor buffer length is 4,278,321,152.

We can avoid this kind of long execution by reducing the size of guest
memory. For example, with 1MB of guest memory, the number of descriptor
entries for processing is limited ~256K.
