While Meson already supports the `-Dbreaking_changes=true` option, it only wires up the build option that propagates into the tests. The build option is only used for our tests to enable the `WITH_BREAKING_CHANGES` prerequisite though, and does not influence the code that is actually being built. The omission went unnoticed because we only have tests right now that get disabled when breaking changes are enabled, but not the other way round. In other words, we don't have any tests that verify that breaking changes behave as expected. Fix the build issue by setting the `WITH_BREAKING_CHANGES` preprocessor macro when breaking changes are enabled. Note that the `libgit_c_args` array is defined after the current spot where we handle the option, so to not have multiple sites where we handle it we instead move it after the array has been defined.
