A lib with 'nopreload' option in public.libraries.txt is not preloaded
during zygote. This is useful for seldom used public libraries; they
don't contribute to the zygote startup time and only affect the apps
that they are used.

Don't create anonymous namespace separately, use the first namespace
that is created for app classloader as the anonymous namespace.
Note that the anonymous namespace is set via the new
ANDROID_NAMESPACE_TYPE_ALSO_USED_AS_ANONYMOUS. I didn't creat a new
function like android_set_anonymous_namespace as it requires uprev of
the libnativebridge interface and makes it harder to delete the old
android_init_anonymous_namespace as we have to keep it until all
proprietary bridged loaders are updated.

This fixes a regression caused by 8f4afc8298
that libnativeloader can't no longer handle the case that it has failed
to find the default namespace. Previously before the change,
libnativeloader continued to use nullptr as the parent namespace which
is reconized as the default namespace inside the linker.
This change recovers the previous behavior. When the default namespace
is not found, NativeLoaderNamespace object is constructed from nullptr.

When a new namespace is added to ld.config.txt, it has to be reflected
to native_loader_test.cpp. However, failing to do so crashes the test
instead of showing an error message that the namespace hasn't been
added.
Fixing the issue by not returning nullptr when the namespace isn't
found.

This affected binaries in the Runtime APEX, where the platform namespace is
"platform" rather than "default".
Also extend ANDROID_ADDITIONAL_PUBLIC_LIBRARIES to create links to both to
platform and runtime namespaces, so that it can be used to open up access to
internal libraries in the Runtime APEX as well, which is used by ART gtests

Also update some comments in the ld.config*.txt files to accurately explain
why some namespaces need to be visible, and some other minor changes for
consistency. There are no semantically significant changes in those files.

Create the anonymous namespace only from a non-empty library path.
This is a better heuristic than the current "first-come" one. It
allows creating classloaders that are not directly related to an
app's "main" classloader, that is, do not have any library path.
This is the case, for example, for shared libraries, including
preloaded ones.
Longer-term, the anonymous namespace creation should be made
explicit, so that the framework can have full control.

Passing nullptr as parent namespace to android_create_namespace makes it use
the namespace of the caller as parent, which typically is the runtime
namespace. That in turn causes classloader-namespace to inherit any
libraries in the shared group of the runtime namespace, i.e. any libraries
that have been loaded in it with RTLD_GLOBAL or DF_1_GLOBAL up to that
point.
Let's instead pass the platform namespace from the linker config as fallback
when a parent namespace cannot be found. That is also what happened before
libnativeloader moved into the runtime namespace.

libnativeloader_lazy and libnativebridge_lazy are shim libraries for
libnativeloader and libnativebridge, respectively.
The shim libraries provides the same APIs as their counterparts, but
when the APIs are called, the APIs from the real libraries are
