[build] Allow for building EFI ISOs without syslinux

The isohybrid tool (that creates a partition table to describe the ESP
embedded within the ISO image) relies upon the existence of the
x86-only isolinux.bin file. This file may not be available on non-x86
build hosts.

We already allow for the possibility that isohybrid may not be present
on the build host, in which case we fall back to creating a non-hybrid
ISO image. Make a similar allowance for the possibility that the
isolinux.bin file may not be present: require its existence only if we
are attempting to build a BIOS-bootable image, or if we will be
attempting to use isohybrid to create a hybrid ISO image.

[console] Avoid overlap between special keys and Unicode characters

The special key range (from KEY_MIN upwards) currently overlaps with
the valid range for Unicode characters, and therefore prohibits the
use of Unicode key values outside the ASCII range.

Create space for Unicode key values by moving the special keys to the
range immediately above the maximum valid Unicode character. This
allows the existing encoding of special keys as an efficiently packed
representation of the equivalent ANSI escape sequence to be maintained
almost as-is.

[efi] Claim fixed device paths by uninstalling device path protocol

As documented in commits 6a004be ("[efi] Support the initrd
autodetection mechanism in newer Linux kernels") and 04e60a2 ("[efi]
Omit EFI_LOAD_FILE2_PROTOCOL for a zero-length initrd"), the choice in
Linux of using a fixed device path requires bootloaders to allow for
the fact that a previous bootloader may have already installed a
handle with the fixed device path.

We currently deal with this situation by reusing the existing handle,
replacing the EFI_LOAD_FILE2_PROTOCOL instance with our own. Simplify
the code by instead uninstalling the EFI_DEVICE_PATH_PROTOCOL instance
from the existing handle (if present), thereby allowing the creation
of a new handle to succeed.

Create the new handle only if we have a non-empty initrd to provide.
This works around bugs in bootloaders such as the systemd EFI stub
that fail to allow for the existence of multiple-bootloader chains.
(The workaround is not comprehensive: if the user has downloaded other
images in iPXE before invoking the systemd Unified Kernel Image (UKI),
then the systemd EFI stub will still crash and burn since it fails to
allow for the fact that a previous bootloader has already installed a
handle with the fixed device path.)

[build] Respect value of $(CC) variable

On FreeBSD the gcc package installs a versioned binary such as
"gcc12". There is no plain "gcc" binary.

Simplify building on such systems by respecting the $(CC) variable.
