installd: add dex2oat cpu-set system properties 

The naming for these follows the convention of the dex2oat-*thread
system properties:

 dalvik.vm.dex2oat-cpu-set [default compiler thread affinity]
 dalvik.vm.boot-dex2oat-cpu-set [compiler thread affinity for boot]
 dalvik.vm.image-dex2oat-cpu-set [thread affinity recompiling the boot image]

Bug: 141446571
Test: add cpu-set properties to target/product/sdk_phone_x86.mk;
Test: lunch sdk_phone_x86-userdebug; m; emulator &
Test: atest -s emulator-5554 --test-mapping frameworks/native/cmds/installd:presubmit
