[profiler] Fix coverage profiler on macos (mono/mono#17396)

If we have coverage profiling enabled for a method (mono_profiler_coverage_instrumentation_enabled, with coverage_filter callback), then we should be able to allocate a coverage info structure (mono_profiler_coverage_alloc). After https://github.com/mono/mono/commit/mono/mono@52429673dc617fd437518757c04c7448211075e9, coverage_filter was reporting wrapper methods as ok to profile, while mono_profiler_coverage_alloc was refusing to allocate the necessary structure, leading to crashes.
