spapr: nested: Add Power11 capability support for Nested PAPR guests in TCG L0
The Power11 architected and raw mode support in Linux was merged via [1]
and the corresponding support in QEMU is waiting to be added by [2]
which in V6 currently.
Add the Power11 capabilities and the required handling in TCG L0
implementation of the "Nested PAPR API".
Note: This patch is based on [2].
