feat(qemu): enable FEAT_ECV when present

Browse source 
QEMU supports FEAT_ECV since commit 2808d3b38a52 ("target/arm: Implement
FEAT_ECV CNTPOFF_EL2 handling"), in the v9.0.0 release. Enable
auto-detecting the feature on the QEMU platforms, in order to set
SCR.ECVEN. Without this, EL2 gets undefined instruction exceptions when
trying to access the new CNTPOFF register.
