Hi,

'sha' is defined in RVA22 as "augmented hypervisor extension" and
consists of a set of named features that must be enabled.

RVA23 makes 'sha' mandatory, so let's add official support for it in
preparation to support RVA23 later. 

Most of the named features added here are always implemented by TCG.
Only 'ssstateen' has a runtime dependency.
