build: disable fuzztest when building with TSAN

Browse Source 
fuzztest's coverage instrumentation is incompatible with Thread
Sanitizer. Add px4_setup_gtest_without_fuzztest() macro to
cmake/px4_add_gtest.cmake that fetches GTest standalone and stubs out
fuzztest cmake functions. Guard all fuzztest-specific code on
TARGET fuzztest::fuzztest so it compiles cleanly without fuzztest.
