BIND_IMS_SERVICE is exposed to vendors

Add vendorPrivileged flag to the permission so that privileged vendor
apks can obtain the permission.

Bug: 35301609
Test: `mm` under frameworks/base/tests/privapp-permissions
adb sync && adb reboot
adb shell cmd package \
com.android.framework.permission.privapp.tests.vendor
shows that the app is installed.
android.permission.BIND_IMS_SERVICE is in the installed permissions list
android.permission.MANAGE_USE is not in the installed permissions list,
but is in the requested permissions list.
