[CDash] [CTest] [Usage] Ignoring coverage line by GCOV_EXCL_LINE

[Zack Galbreath]

I can't say I have much experience with these markups, but after searching
a bit I found this relevant post on stackoverflow:

https://stackoverflow.com/questions/38618136/lcov-excl-start-stop-has-no-effect-when-using-gcovr

Their solution was to use gcovr v3.4.

I haven't used this tool either, but it looks like it also has an option to
output coverage data in Cobertura XML format:
https://gcovr.com/en/stable/guide.html#getting-started
That's another coverage format that CTest knows how to parse.

Good luck! Let us know how it goes.
