x86/gpu: Add Alderlake-S stolen memory support
Alderlake-S is a Gen 12 based hybrid processor architecture. As it
belongs to Gen 12 family, it uses the same GTT stolen memory settings
like its predecessors - ICL(Gen 11) and TGL(Gen 12). Inherit gen11
and gen 9 quirks for determining base and size of stolen memory.
