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 "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.

Vfkit supports the schemes `unix` and `none` in addition to `tcp`.
Krunkit currently only implements `tcp`, so implement the remaining
schemes to meet vfkit parity.

Update the documentation for the virtio-blk device to be more accurate.
The user may include 1 or more disks, where the first is the root disk
and any subsequent disks will be used as data disks. Also do not restrict
the backing image to be a raw image, as we now support QCOW2.

Version 1.11 of libkrun introduces support for Nested
Virtualization on macOS hosts. Let's add a flag to allow users to
request its enablement.

Update the README.md to give instructions on how to build krunkit from
source assuming all necessary dependencies are installed.

Add an LIBKRUN_EFI variable that will link the specified library with the krunkit binary.
This is only necessary for when the user has built libkrun-efi from source
or if libkrun-efi.dylib is not in /opt/homebrew/lib/.

Updates the argument parsing in src/cmdline.rs to no longer use
`args_parse` or `val_parse`.

Updates the argument parsing for `virtio-blk` to use new helper
functions.
Makes the `format=` argument optional and provides the default value
`raw`.

Link with libkrun's new `krun_add_disk2` API to allow the user to use
either a Raw or Qcow2 disk image.
Adds the `format` argument to the `virtio-blk` device.

Automatically adjust VRAM so VRAM+RAM doesn't exceed the space
available in a 36 bit IPA, accounting for the start address and
rounding in libkrun, which sets an upper limit of ~62GiB.
Also, reject a memory configuration larger than 60 GiB to ensure
we leave some room for VRAM.

On version 1.9.5 libkrun introduced an API to set the size of the
SHM window for virtio-gpu. Use it to set it to be as large as the
host's RAM. This should give us enough room for running large
models, accounting for potential device memory fragmentation.

Use the new krun_add_disk API, introduced in libkrun 1.9.5, to be
able to add an arbitrary number of virtio-blk devices.
