We have a new SBI debug console (DBCN) extension supported by in-kernel
KVM so let us add this extension to get-reg-list test.

When outputting the "new" register list we want to print all of the
new registers, decoding as much as possible of each of them. Also, we
don't want to assert while listing registers with '--list'. We output
"/* UNKNOWN */" after each new register (which we were already doing
for some), which should be enough.

Add a couple macros to use when filling arrays in order to ensure
the elements are placed in the right order, regardless of the
order we prefer to read them. And immediately apply the new
macro to resorting the ISA extension lists alphabetically.

Currently the AIA ONE_REG registers are reported by get-reg-list
as new registers for various vcpu_reg_list configs whenever Ssaia
is available on the host because Ssaia extension can only be
disabled by Smstateen extension which is not always available.
To tackle this, we should filter-out AIA ONE_REG registers only
when Ssaia can't be disabled for a VCPU.

Same set of ISA_EXT registers are not present on all host because
ISA_EXT registers are visible to the KVM user space based on the
ISA extensions available on the host. Also, disabling an ISA
extension using corresponding ISA_EXT register does not affect
the visibility of the ISA_EXT register itself.
Based on the above, we should filter-out all ISA_EXT registers.

get-reg-list test is used to check for KVM registers regressions
during VM migration which happens when destination host kernel
missing registers that the source host kernel has. The blessed
