manifest_check.py: translate library names using dexpreopt configs.

Java modules that are defined in makefiles are not processed in
topological order, so it is necessary to communicate information from
dependencies via dexpreopt.config files. This has already been done in
make/core/dex_preopt_config_merger.py, and now manifest_check.py also
needs to get library names from their dexpreopt.config files.

This is to accommodate Java libraries which name differs from their
modules name. Soong properties `uses_libs`/`optional_uses_libs` and
makefile vars `LOCAL_USES_LIBRARIES`/`LOCAL_OPTIONAL_USES_LIBRARIES`
contain module names, not library names, so it is necessary to translate
them when comparing against library names in the manifest.

Bug: 132357300

Test: lunch cf_x86_64_phone-userdebug && m && launch_cvd \
      adb wait-for-device && adb root && adb logcat \
      | grep -E 'ClassLoaderContext [a-z ]+ mismatch'
      # empty grep output, no errors
