Add '-accel <mode>' and 'no-accel' options.

This patch adds two new options to better control CPU emulation
acceleration (i.e. KVM and HAX). More specifically:

  '-no-accel' can be used to disable acceleration if available.
  '-accel off' does the same.
  '-accel on' forces to run with acceleration, or refuses to start
  the emulator.
  '-accel auto' probes the system for a working accelerator and uses
  it when possible (i.e. when emulating x86 or x86_64 images only).

Also print some information with -verbose or -debug-init.

Note: This adds QEMU-independent probing code for KVM and HAX
      under android/emulation/ (C++), as well as some glue to
      use it from C under android/cpu_accelerator.[hc].

Note: HAX is no longer enabled by default when reaching the QEMU
      main function.
