Adds the "Bootloader Configuration" section to the docs page. Additionaly, it
specifies the option is purely for vfkit parity and does not get processed by
the CLI.

`clean`.

Rather than hardcoding a path to the /opt/homebrew/lib directory for the
build.rs file to link with, we should use the path provided by the user
in LIBKRUN_EFI instead. If the environment variable cannot be found
because a user didn't use it, then fallback to the default path.

Adds the new `type={unixgram, unixstream}` argument. This allows the
user to create an independent unixgram-based or unixstream-based
virtio-net device rather than forcing the user to use gvproxy.

No longer use the deprecated `krun_set_gvproxy_path` when the user
creates a virtio-net device with the `unixSocketPath` argument. Use the
new `krun_add_net_unixgram` API instead.

With the adoption of the new `krun_add_net_unix*` APIs, we no longer
need to manually set the MAC address for the virtio-net device.

Due to a docs bug in vfkit, we have incidentally diverged from vfkit
default behavior by using tcp as the default. Now that the argument
supports none://, that should be the default instead.

Add a new --pidfile option. This will allow the user to specify a path
in which the krunkit binary will write its PID.

With the latest changes, I think it's clear the project has
reached maturity. Make it public by bumping version all the way
to 1.0.0.
