This commit disables ContextCustomizer implementations that tune a
test configuration context at runtime. Previously, these ran again and
required additional hints to work properly.
Rather than contributing those hints, the customizer is skipped as its
impact is irrelevant in an AOT-optimized context: the context is fully
prepared and the updates on the MergedContextConfiguration are not taken
into account.
