fs/squashfs: Add block size option One advantage of squashfs over similar technologies is the support for bigger block sizes. However the default size is not a lot bigger (typically 128k if no `-b` flag specified). This patch adds the ability to select from common block sizes which for example can aid in improving compression ratio.

fs/squashfs: Add option to compress with extreme options mksquashfs allows to tweak many compressions parameters. Currently they can't be changed from kmenu. Leaving out potential space savings. This adds the option to enable a set of predetermined compression options. This option is enabled by default for lz4 since lz4 currently implicitly added the extreme to it in the makefile. So this aids in keeping backward compatibility.

Use options to increase compression ration as much as
possible, like using architecture-specific options, at
the cost of time when assembling the filesystem image.
For example:
- with gzip and lzo, use -Xcompression-level 9
- with xz use arch-specific bcj (branch-call-jump) filters
- with zstd use -Xcompression-level 22
- and more
