Vulnerabilities: Filter out where "Projects = 0"

### Current Behavior:
With a totally fresh install of Dependency-Track 4.2.2, the Vulnerability page very quickly "fleshes out" to display more than 125k rows. This provides a usability issue with getting an overall view of "what is affecting me".

### Proposed Behavior:
Provide a checkbox similar to the " Show inactive projects" displayed on the Projects screen. The checkbox would act to include/exclude all vulnerabilities that have 0 affected projects, with the suggested default being to exclude. This would reduce the displayed listing from 125k to a (hopefully) a nice low number. Even if there 1000 vulnerabilities it would still only take 10 clicks to navigate from beginning to end with display set to 100 per page.

One use case for this suggested functionality is that it would make it possible to sort vulnerabilities by "Published" and then simply scroll down to see the most recent vulnerabilities to appear in the portfolio. Useful should notifications be unconfigured (or directed to the wrong people, etc).
