When we haven't downloaded an image via mem{disk,cd} and ipxe, try any
image specified by the FreeBSD-specific initmd dhcp option. This allows
direct booting of loader.efi with a detached root ramdisk filesystem.

Configure net0, read the DHCP-provided initmd URL, and download it
through the file API so directly booted loader.efi can construct its

loader.efi: For ipxe booting, fall back to md when ramdisk fails
Some UEFI firmwares do not contain the RamDisk protocol. When this
happens, load the file into a md disk instead. This is less desireable
than the RamDisk (since that allows better chain-booting options), but
sufficient to boot an image as a md device for FreeBSD. While most
severs have the RamDisk protocol enabled in their builds, I have two
IoT class boards from different manufacturers that do not. Since it
works just fine with this fallback, that's preferable.

loader: Add xzfs support by defualt to BIOS and EFI loaders
For the BIOS, add xzfs support. This is a tiny increase in the loader
size, but allows us to fetch compressed files from any of the
filesystems we support, including over the network.
For EFI, also add gzipfs and bzip2fs support we well. The increment for
these files is tiny.

This reverts commit 3e3fd1fde8e168910edc538966111c0b5f03cd5f.
This appears to break chainbooting with boot1.efi and similar scenarios
with Root-on-ZFS scenarios. Revert until it's better understood.

loader.efi: Recognize new memdisk=<url> and memcd=<url> options
Support ipxe downloading of a memory disk (either presented to the OS as
a harddisk or a cd). This requires an ipxe server since it uses the ipxe
download protocol to grab the disk. If there is a disk, we add it to the
environment as a disk, and then the rest of the bootloader just sees it
and boots from it.
I've cribbed code from https://github.com/russor/memdisk_uefi and
adapted it to work in the context of the FreeBSD bootloader.
The ipxe_download.h file was created from the documentation of the
interface.
So a .ipxe file with the line
chain http://10.2.0.1/loader.efi memdisk=${cwduri}FreeBSD-15.1-RELEASE-amd64-bootonly.iso
would use the FreeBSD boot loader to boot the FreeBSD 15.1 release.
md(9) has a bug at the moment that prevents it from probing the
partitions on it.
Also, we'll automatically decompress gzip, bzip2 and zstd files
automatically.

loader.efi: Trim ZFS searching for other booting options
When we're searching the system for all the disks in relaxed mode, we
need to do a final pass over all the non-boot disks. We no longer need
to have two loops since ZFS on boot device is selected properly in
try_boot_device_partitions. This also simplifies the code a bit.
