Implement FEAT_SME and most optional extensions, which are really
pretty trivial compared to the main feature. FEAT_EBF16 is still
on the to-do list.
Includes linux-user support, based on Mark Brown's code that has been
merged into linux 5.19-rc1.
Mark's kselftest suite is in fact all of the testing that I have done,
since the current public Arm FVP does not include support for SME.
On the bright side, Mark's tests handle all of the new mode switching,
which IMO is the hairy part, and wouldn't be tested by RISU anyway.
All prerequisites are either merged or dropped.
