Documentation/hw-vuln: Document the interaction between IBRS and STIBP
commit e02b50ca442e88122e1302d4dbc1b71a4808c13f upstream.
Explain why STIBP is needed with legacy IBRS as currently implemented
(KERNEL_IBRS) and why STIBP is not needed when enhanced IBRS is enabled.
Fixes: 7c693f54c873 ("x86/speculation: Add spectre_v2=ibrs option to support Kernel IBRS")
