Support /product-services partition

This CL is largely an adaptation of Change-Id
I16175933cebd9ec665d190cc5d564b5414a91827 . I also used the same way for
testing the change.

This CL will support the followings.
- installing a RRO package for framework from /product-services/overlay
- installing apps from /product-services/app
- installing priv-apps from /product-services/priv-app
- installing permissions from
  /product-services/etc/[default-permissions|permissions|sysconfig]

Bug: 80741439
Test: `mm` under frameworks/base/tests/[libs|privapp]-permissions
  adb sync && adb reboot
  adb shell cmd package list libraries
    => confirmed com.android.test.libs.product_services library
  adb shell cmd package dump \
    com.android.framework.permission.privapp.tests.product_services
    => confirmed that the package is a priv-app

  And I moved vendor/overlay/framework-res__auto_generated_rro.apk
  into system/product-services/overlay/ on taimen, and I confirmed that the
  RRO was installed properly.
