Use the profiles in the APEX to dexpreopt system server jars.

After this change, if "profile_guided: true" is set, profile-guided
compilation will be enabled for the jar and the ".prof" file next to
the jar in the APEX ("javalib/<name>.jar.prof") will be used as the
profile when dexpreopting for the prebuilt APEX.

Bug: 241823638
Test: m nothing
Test: -
  1. (on internal master) Patch aosp/2426453.
  2. Build the APEX bundle and the module SDK of com.android.wifi
  3. (on tm-dev) Patch this CL and aosp/2141972.
  4. Copy the APEX bundle and the module SDK built on step 2 to the
     source tree
  5. Disable hiddenapi check
  6. lunch cf_x86_64_phone-userdebug && m MODULE_BUILD_FROM_SOURCE=false com.google.android.wifi
  7. cat out/soong/.intermediates/prebuilts/module_sdk/Wifi/current/prebuilt_service-wifi/android_common_com.android.wifi/dexpreopt/oat/x86_64/javalib.invocation
  8. See the profile being used.
