api-client: Refactor to removed hard-coded prefix

Browse Source 
The existing API client only allows access to "VM" operations, so added
a new `simple_api_full_command_with_fds()` that allows access to "VMM"
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()`.

Fixes: #4701.
