CTest: Add support for Intel coverage files

By default, Intel compiler coverage tools generate HTML files as
reports, but the option -txtlcov can be given to codecov to output a
coverage file with LCov format.

To use Intel coverage:

* build the project with coverage flags
* run the application
* run profmerge
* run codecov

The output file will be "build_dir/CodeCoverage/SRCFILEDIR.LCOV".

Ask users to compile with -prof-dir${BUILD_DIR} instead of searching
the entire build tree recursively to find coverage files.
