drm/amdgpu: add RAP TA header file

Browse Source 
The RAP TA contains tests used to verify if
RAP(Register Access Policy), or otherwise known
as Security Policy is applied correctly
by PSP BL&TOS.

The RAP test is a measure to ensure that we reduce
the avenue of complexity and mistakes when dealing
with RAP in post-si execution, where debugging failures
related to RAP is quite difficult and expensive.

v2: add introduction for RAP TA
