redhat/configs: enable CONFIG_SQUASHFS_ZSTD which is already enabled in Fedora 34

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1998953
Upstream Status: RHEL-only

Kdump will use ZSTD as the default method for initrd squashfs compression. It is helpful
for reducing the vmcore dump and read time consumption while keeping a good compression
ratio on machines with large memories. Fedora has already enabled CONFIG_SQUASHFS_ZSTD,
this patch enables CONFIG_SQUASHFS_ZSTD for RHEL by removing
configs/ark/generic/CONFIG_SQUASHFS_ZSTD
and moving configs/fedora/generic/CONFIG_SQUASHFS_ZSTD to configs/common/generic.

I don't see the approve button in my view of this MR for some reason. This
change looks good to me, ACK.

Tao, thanks for doing this in ARK.  If you haven't already, you'll also 
have to do this for rhel-9/centos-stream-9.
