tasks/lvm: add all tools from thin-provisioning-tools

[ajs124]

Motivation for this change

This should barely increase the size of the initrd, because these are all symlinks.
With this, systems with dm-cache/lvmcache can also be booted, although the kernel modules for the relevant dm targets still need to be added to the initrd with boot.initrd.kernelModules.

Closes #46541

I'd love to get some feedback or more testing for this, but if no-one replies, I'll probably merge it in a week or two.
