  1. kernel-5.10: Allow handling of compressed firmware 

    Firmware binary blobs can add up to quite a lot of disk space usage.
With Bottlerocket we do aim to keep our images small, so enable the
kernel's firmware loading infrastructure to handle compressed firmware
files.

  3. kernel-6.1: Allow handling of compressed firmware 

    Firmware binary blobs can add up to quite a lot of disk space usage.
With Bottlerocket we do aim to keep our images small, so enable the
kernel's firmware loading infrastructure to handle compressed firmware
files.

Previous to linux kernel series 5.19 option `CONFIG_FW_LOADER_COMPRESS`
was only supporting the XZ compression algorithm. Since then also ZSTD
compression is available which makes additional options necessary to
select the right algorithm. For now select the default XZ compression
to align all our supported kernels on the same. Once we are only
supporting kernels >=6.1 we may chose to switch compression algorithm.

  4. linux-firmware: Enable firmware compression 

    Recoup some image size by enabling firmware compression, now that our
kernels support it.

None of the compressed firmware files has the execute bit set, so we can
skip removing it when assembling the package.
