count all materialized vulnerabilities for metrics

[stohrendorf]

Description

Changes metrics calculations to count all materialized vulnerabilities for every metric instead of counting virtual (aliased) vulnerabilities in one case and materialized vulnerabilities in other cases.

Addressed Issue

Fixes #4261

Additional Details

I opted for counting all materialized vulnerabilities to avoid confusion when some analyses for a virtual vulnerability would be counted as audited, while others wouldn't.
