Ability to add exclusions to grcov

[xnuter]

Added ability to provide the following parameters via config:

        --excl-br-line <regex>
            Lines in covered files containing this marker will be excluded from branch coverage.

        --excl-br-start <regex>
            Marks the end of a section excluded from branch coverage. The current line is part of this section.

        --excl-br-stop <regex>
            Marks the end of a section excluded from branch coverage. The current line is part of this section.

        --excl-line <regex>
            Lines in covered files containing this marker will be excluded.

        --excl-start <regex>
            Marks the beginning of an excluded section. The current line is part of this section.

        --excl-stop <regex>
            Marks the end of an excluded section. The current line is part of this section.
