W-23475825 build(native-lib): strip debug symbols and add libdwlib symlink#125

…mlink
Two build improvements to the shared native library (dwlib) consumed by the
existing Python and Node bindings, extracted from the native-bindings branch
as an independent change:
- stripNativeLibrary: strip debug symbols from dwlib after nativeCompile to
reduce artifact size (strip -S on macOS, --strip-debug on Linux, best-effort
on Windows). Skippable with -PskipStripDebug=true for local debugging.
- On Linux/macOS, create a libdwlib.{so,dylib} symlink so consumers can link
with the standard -ldwlib flag.
The stagePythonNativeLib and stageNodeNativeLib tasks now depend on
stripNativeLibrary so both existing bindings package the stripped library.
Verified with a real GraalVM native build: nativeCompile -> stripNativeLibrary
("Stripped debug symbols") -> stagePythonNativeLib succeeds, libdwlib.dylib
symlink is created, and the stripped lib is staged.
