feat(cpufeat): enable FEAT_BTI to FEAT_STATE_CHECKED
Introduce the is_feat_bti_{supported, present}() helpers and replace
checks for ENABLE_BTI with it. Also factor out the setting of
SCTLR_EL3.BT out of the PAuth enablement and place it in the respective
entrypoints where we initialise SCTLR_EL3. This makes PAuth
self-contained and SCTLR_EL3 initialisation centralised.
