Rework the coverage build
This reworks it to avoid a need to special build type and adding the flags only to the targets that need it (skipping testing wrappers which break with them). It also updates the CodeCoverage module from the following URL: https://github.com/bilke/cmake-modules/blob/master/CodeCoverage.cmake Signed-off-by: Jakub Jelen <jjelen@redhat.com> Reviewed-by: Andreas Schneider <asn@cryptomilk.org>

# - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
|

# This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".

# USAGE:
