RFR: 8356116: [macos] Add logging of sign commands in jpackage [v2]

[Alexander Matveev]

> - Added logging of sign commands.
> - Sign commands will be logged with `DEBUG` level. Skipped files and signature removal with `TRACE` to reduce amount of less important messages.
> - Renamed `unsign` to `removeSignature`. I think it is better name.
> - Removed `sign` and `codesigners.accept(path)` will be used instead. Not sure why we need function with one line and we using `codesigners.accept(path)` in other places anyway.
> - Direct call to `codesigners.codesignDir().accept(path)` was changed to `codesigners.accept(path)`. In this case exception will be logged if `codesignDir` is not available and I think it is better for `codesigners.accept(path)` to select code signer vs calling it directly.
