Use 'long' for execution counts in coverage output

It is possible in large projects for tests to trigger the execution of
some lines or functions more than 2^31-1 times (the signed int limit).
In these cases, combining merging reports will produce nonsense
outputs, perhaps even negative counts, or simply fail to parse the JSON
gcov output if a single test file triggers the problem.

Fixes #11052

Closes #11894.
