FYI I couldn't address all comments from previous iterations,
so plan to revisit and self-review some patches, improving
commit descriptions. Still good enough for review / testing IMO.

Since v1:
- Addressed Mads & Richard comments
- Fixed migration by reworking memory listeners
  (unfortunately the current broken code has been
   used as base for WHPX)
- Sync CNTV_CTL/CVAL_EL0
- Remove WFI racy signal implementation
- Simplify PSCI Suspend (I expect the same can be
  done for the other hvf_psci_cpu_off() calls).
- Emulate more missing registers (PMU & Monitor Dbg)

From v1:
- Fix a pair of memory leak
- Check a pair of return values
- Mention calls which must be run on vCPU thread
- Force MIDR
- Use hv_vcpu_config_create/hv_vcpu_config_get_feature_reg
  when not running on vCPU thread
- Factor hvf_handle_vmexit() / hvf_handle_exception(() out
- Call hv_vcpu_run() in loop
- Guard hv_vcpu_run() between cpu_exec_start/end()
- Restrict ARM specific in AccelCPUState
