RFR: 8351073: [macos] jpackage produces invalid Java runtime DMG bundles

[Alexander Matveev]

Fixed jpackage to produce valid Java runtimes based on description below:

Definitions:

- JDK bundle defined as bundle which contains "Contents/Home", "Contents/MacOS/libjli.dylib" and "Contents/Info.plist".
- Signed JDK bundle contains all files as JDK bundle + "Contents/_CodeSignature".
- JDK image defined as content of "Contents/Home".
- Signed JDK image does not exist, since it cannot be signed as bundle.

jpackage output based on input:

1. "--runtime-image" points to unsigned JDK bundle and --mac-sign is not provided:
- jpackage will copy all files as is from provided path and run ad-hoc codesign.

2. "--runtime-image" points to unsigned JDK bundle and --mac-sign is provided:
- jpackage will copy all files as is from provided path and run codesign with appropriate certificate based on same logic as we do for application image.
 
3. "--runtime-image" points to signed JDK bundle and --mac-sign is not provided:
- jpackage will copy all files as is from provided path including "Contents/_CodeSignature" to preserve signing.

4. "--runtime-image" points to signed JDK bundle and --mac-sign is provided:
- jpackage will copy all files as is from provided path including "Contents/_CodeSignature" and will re-sign bundle with appropriate certificate.

5. "--runtime-image" points to JDK image and --mac-sign is not provided:
 - jpackage will check for libjli.dylib presence in "lib" folder.
 - Create JDK bundle by putting all files from provided path to "Contents/Home", libjli.dylib from "lib" to "Contents/MacOS/libjli.dylib" and create default "Contents/Info.plist" similar to what we do for runtime in application image.
- Ad-hoc signing will done.

6. "--runtime-image" points to JDK image and --mac-sign is provided:
- 2 first steps from 5 and certificate signing will be done.
