target/arm: Implement FEAT_ECV CNTPOFF_EL2 handling
When ID_AA64MMFR0_EL1.ECV is 0b0010, a new register CNTPOFF_EL2 is
implemented. This is similar to the existing CNTVOFF_EL2, except
that it controls a hypervisor-adjustable offset made to the physical
counter and timer.
Implement the handling for this register, which includes control/trap
bits in SCR_EL3 and CNTHCTL_EL2.
