Bug 1122: Add AArch64 support (Android, GNU/Linux and in general)

- Add AArch64 detection via
  - Elf Parser
  - Android properties
  - Java properties
  - Android: Validate CPUType.Family _and_ ABIType

- MachineDescription
  - Remove redundant Type ID and its field
  - Reuse X86_64_UNIX for AArch64 (static config)

New ARCH 'aarch64' for
  ant: <os arch>
    armv8a
    aarch64

 New CPUType.ARM64 (ARM):
  java: os.arch
    aarch64
    arm64

 New CPUType.ARMv8_A (ARM):
  java: os.arch
    armv8-a
    arm64-v8a

New ABIType:
  EABI_AARCH64
