Issue:
[REQ] Multi Platform Summary Enhancement
### What kind of request is this?

None

### What is your request or suggestion?

Change "ERROR" field in multi arch summary report to "MESSAGE".  This can specify why the image was not patched. For example "No scanner report", "Windows image", or an error message if there was an error during patch.

### Are you willing to submit PRs to contribute to this feature request?

- [ ] Yes, I am willing to implement it.

Pull request description:
feat: enhance multi platform summary report
Updated ERROR column naming to MESSAGE.
Also added the "No windows supported" error

Currently if we don't provide reportFile for an image under the mutliArch patching it doesn't return an error and just logs a WARN message about no VEX Report creation (through singleArchPatch) and continues patching in the update all method.
I added a "No Scanner Report" error where the patching for that image will be ignored and we'll show that image with "No scanner report" in the tabular summary.

Closes #1122
