Coverage CI multi-threaded tests

[qualand]

Coverage CI does not work with any multi-threaded tests. Currently, these tests are turned off for coverage CI.

Original error:

geninfo: ERROR: Unexpected negative count '-1744992' for /home/runner/work/SolTrace/SolTrace/coretrace/simulation_runner/native_runner/treemesh.cpp:256.
	Perhaps you need to compile with '-fprofile-update=atomic
	(use "geninfo --ignore-errors negative ..." to bypass this error)

Adding -fprofile-update=atomic to the cmake CXX_FLAGS

        -DCMAKE_CXX_FLAGS="--coverage -fprofile-update=atomic"

Results in a mismatch error

geninfo: ERROR: mismatched end line for _ZN54HeliostatFieldSimulation_singleFacet_SlantFocused_Test8TestBodyEv at /home/runner/work/SolTrace/SolTrace/google-tests/unit-tests/simulation_data/cst-templates/heliostat_field_test.cpp:875: 875 -> 887
	(use "geninfo --ignore-errors mismatch ..." to bypass this error)

Adding --ignore-errors mismatch results in multiple warnings about mismatch and unexecuted block and eventually errors out with negative count.

It would be nice for coverage to handle multi-thread tests.
