Add hidden API properties to java_sdk_library modules

Previously, hidden API properties were only allowed on
bootclasspath_fragment and platform_bootclasspath module types. This
change allows them to be specified on java_sdk_library modules too. It
involves the following changes:

1. Add the properties to the java.Module.
2. Populate and provide a HiddenAPIPropertyInfo struct from
   java_sdk_library modules.
3. Modify bootclasspath_fragment to merge information gathered from its
   content libraries as if it was specified on the fragment itself.

Bug: 240406019
Test: m nothing
      packages/modules/common/build/mainline_modules_sdks.sh
      # Ran the previous command with and without this change to make
      # sure that this change does not change the sdk snapshot
      # contents.
