Report Fixed State of Vulnerabilities

**Is your feature request related to a problem? Please describe.**

I'd like to be able to filter out vulnerabilities for which no fix is available by upgrading the dependency, so I can present them differently compared to vulnerabilities which can be fixed by upgrading the version of the dependency.

**Describe the solution you'd like**

Include the fixed status for each vulnerability in the Dependency Check json output.

**Describe alternatives you've considered**

The `grype` output (also available in json format) includes the version in which the CVE is fixed:

```
NAME INSTALLED FIXED-IN VULNERABILITY SEVERITY
apk-tools 2.10.6-r0 2.10.7-r0 CVE-2021-36159 Critical
libcrypto1.1 1.1.1k-r0 CVE-2021-3711 Critical
libcrypto1.1 1.1.1k-r0 CVE-2021-3712 High
libssl1.1 1.1.1k-r0 CVE-2021-3712 High
libssl1.1 1.1.1k-r0 CVE-2021-3711 Critical
```

The output from `trivy` (also in json format) includes information about the fixed status as well.

Additionally `trivy` has an `--ignore-unfixed` flag and `grype` has an `--only-fixed` flag.

My request is for the Dependency Check json output to also include the fixed status of a CVE.

**Additional context**

I'm not sure if this data (fixed version) is available in the data sources used by Dependency Check.
