slimboot: add recipe for Slim Bootloader

Slim Bootloader is an open-source boot firmware running on Intel x86
architecture.

Currently it supports qemu, apl(Apollo Lake), cfl(Coffee Lake),
cml(Comet Lake), tgl(Tiger Lake), and ehl(Elkhart Lake). You can set
"SLIMBOOT_TARGET" in .bb file or .bbappend file to specify or add the
target firmware you want, for example: SLIMBOOT_TARGET = "qemu apl".
The default target is qemu.

Generated firmware and security keys are installed in build directory:
    image
    `-- usr
        `-- libexec
            `-- slimboot
                |-- Outputs
                |   |-- qemu
                |   |-- apl
                |   `-- cfl
                `-- keys

Boot firmware for qemu can be used by command:
"qemu-system-x86_64 -machine q35 -nographic -serial mon:stdio -pflash
SlimBootloader.bin"

Other boot firmware for real hardware cannot be programmed directly to
flash, please refer to https://slimbootloader.github.io/index.html for
more instructions.
