RFR: 8355080: java.base/jdk.internal.foreign.SystemLookup.find() doesn't work on static JDK [v2]

[Jiangli Zhou]

> Please review this PR that changes to use `NativeLibraries.loadLibrary()` for loading the `libsyslookup` in `jdk.internal.foreign.SystemLookup` class.
> 
> `NativeLibraries.loadLibrary()` handles both the shared library and (static) built-in library loading properly. On `static-jdk`, calling `NativeLibraries.loadLibrary()` for `systlookup` library can find the built-in library by looking up using `JNI_OnLoad_syslookup`. The current change adds `DEF_STATIC_JNI_OnLoad` in syslookup.c (in shared, windows and aix versions) for that purpose.
> 
> In addition to GHA testing, I tested the change on static-jdk with jdk tier1 tests on linux-x64 locally. All java/foreign/* jdk tier1 tests pass with the change. Without the change, there are about 60 java/foreign/* jdk tier1 tests fail on static-jdk.

Jiangli Zhou has updated the pull request incrementally with one additional commit since the last revision:

  Update src/java.base/share/classes/jdk/internal/foreign/SystemLookup.java
  
  Thanks.
  
  I used `jdk.internal.loader.NativeLibraries` as a quick change before adding adding import. I neglected to to clean up that part.
