Revert "Don't add `uses_libs`/`optional_uses_libs` to the manifest_fixer."

This reverts commit 0b1c70efbcbb0c8408f44964923f5b156d025936.

The reverted commit was based on the idea that uses-libraries that are
explicitly specified in build files should not be implicitly added to
the manifest, as that would mean that anything added to the build files
will flow to the manifest.

Although this logic is correct, it prevents propagation of
uses-libraries from dependencies, which is wrong: if a library has an
explicit uses-library property in Android.bp, this property is expected
to be propagated to the library's dependencies. Failing to do so would
mean that every user of that library has to add uses-library property to
their build files, which doesn't scale (see b/214255490 for example).

Bug: 214255490
Test: lunch aosp_cf_x86_64_phone-userdebug && m && launch_cvd \
    && adb wait-for-device && adb root \
    && adb logcat | grep -E 'ClassLoaderContext [a-z ]+ mismatch'
    # empty output, no errors at boot
