For dynamic linking perspective, semantics of NativeBridge needs to
align with dynamic linker. This patch adds "linked namespace" semantic
which shares some libraries from one namespace to another.

Prevent the boot from failing silently if one of the public libraries
does not exist.
Test: Add invalid element to public libraries and observe log is emited
during boot failure.

This allows clients creating their own namespace do so by modifying
the default library path, rather than hardcoding it multiple places in
the system.

libutils, libz and libbase are being used as shared lib by many other
modules.
So using their shared lib will reduce total image size.
Size diffs on angler build image are as follows.
libziparchive.so : 103844 -> 41680 (-62164)
libnativeloader.so: 50824 -> 25104 (-25720)
total : (-87884)
Test: building succeeded, and the image was tested on angler.

This function is always called by the frameworks in order to
initialize vulkan layer path. For NB apps returning nullptr

Native bridge implements namespace related interfaces in version 3.
The namespace semantic here is same as Android dynamic linker's.
Native loader wraps library loading functions of dynamic linker and
native bridge. Thus, Android runtime is able to load native library
of different ISA on one device by calling native loader directly.

For public vendor libraries, a vendor might have only a 32 bit
or only a 64 bit version of the library. Add a way to indicate this
in the public.libraries.txt files. The new format is:
library.so 32
This indicates that this is a 32 bit only public library.
library.so 64
This indicates that this is a 64 bit only public library.

LOCAL_LDLIBS should only be used with -l flags for NDK and some host
libraries. Other uses should use LOCAL_SHARED_LIBRARIES.
LOCAL_LDFLAGS should not contain -l entries, they should be in
LOCAL_LDLIBS instead.
LOCAL_CFLAGS should not contain -I entries, those should use
LOCAL_C_INCLUDES instead.

Since linker-namespaces are enabled for all target_sdk_versions
and there is no longer need in workarounds in libnativeloader -
remove unused target_sdk_version parameter for internal calls.
This also brings libnativeloader closer to aosp/master

This change allows applications to share RTLD_GLOBAL
native libraries between namespaces associated with
different classloaders.
The rule is - if a library is GLOBAL within namespace
associated with parent classloader, it is shared
with namespace associated with this classloader
Note that the sharing happens on create_namespace
event, which is tied to createClassloader in case of
application classloaders created by the framework, for
custom application classloaders it is tied to first
loadLibrary() event.

Now that we have the fixed list of whitelisted libraries
there is no longer need to check if java_permitted_path is nullptr.
In fact checking it prevents custom classloaders created by apps
from loading libraries using absolute path.
