[jdk11u] RFR: 8275703: System.loadLibrary fails on Big Sur for libraries hidden from filesystem

[Goetz Lindenmaier]

I backport this for parity with 11.0.15-oracle.

The code touched was completely reworked in jdk15 by "8228336: Refactor native library loading implementation"

make/test/JtregNativeJdk.gmk
Trivial resolve due to context.

src/hotspot/share/prims/jvm.cpp
Applies clean, but does not compile.
I removed "log_info(library)("Failed to load library %s", name);"
Logging was only added to this file in jdk15 with "8187305: Add logging for shared library loads/unloads"

Changes to 
src/java.base/macosx/classes/jdk/internal/loader/ClassLoaderHelper.java
applied to 
src/java.base/macosx/classes/java/lang/ClassLoaderHelper.java
Fits well.

Changes to 
src/java.base/share/classes/jdk/internal/loader/NativeLibraries.java
applied to class NativeLibrary in java/lang/ClassLoader.java.
I had to modify the code.

Changes to 
src/java.base/share/native/libjava/NativeLibraries.c
applied to 
src/java.base/share/native/libjava/ClassLoader.c
Fits acceptable.

Changes to
src/java.base/unix/classes/jdk/internal/loader/ClassLoaderHelper.java
applied to 
src/java.base/unix/classes/java/lang/ClassLoaderHelper.java
Fits well.

Changes to
src/java.base/windows/classes/jdk/internal/loader/ClassLoaderHelper.java
applied to 
src/java.base/windows/classes/java/lang/ClassLoaderHelper.java
Fits well.

SAP testing passed.
