[Feature] Break out LCOV test coverage into its own test configuration

[gcampbell-msft]

Request Overview

The LCOV tests add a requirement that LCOV be installed on the system. This is fine for the LCOV tests, but I don't like the dependency that it creates for all of the other single-root-UI tests.

I want to break it out into its own configuration so that I only have to install LCOV (or make local changes), if I want to test LCOV, which has the requirement of installing LCOV on the system.
