Description
Trying to build 32-bit builds that do not enable `INCLUDE_CDS_JAVA_HEAP` would fail during the build on this assert:

```
#  Internal Error (/home/buildbot/worker/build-jdkX/build/src/hotspot/share/cds/archiveBuilder.cpp:900), pid=267008, tid=267017
#  assert(HeapShared::is_lambda_proxy_klass(ik)) failed: sanity
#
# JRE version: OpenJDK Runtime Environment (24.0) (fastdebug build 24-internal-adhoc.buildbot.build)
# Java VM: OpenJDK Server VM (fastdebug 24-internal-adhoc.buildbot.build, interpreted mode, g1 gc, linux-arm)
# Problematic frame:
# V  [libjvm.so+0x2a3db8]  ArchiveBuilder::make_klasses_shareable()+0x15d0
```

That assert was added by JDK-8331497. Unfortunately, with `!INCLUDE_CDS_JAVA_HEAP`, `HeapShared::is_lambda_proxy_klass` would be compiled as unconditional `false`, which is guaranteed to fail the assert.

I think the minimal fix to unbreak the builds is wrapping those asserts into appropriate macros.
