This enables minimal Ubsan with other sanitizers. It's accomplished by removing restrictions of `-fsanitize-minimal-runtime` and linking minimal Ubsan into full Ubsan and other sanitizers where full Ubsan is used.

As discussed in [1] the motivation here is to reduce the code bloat caused by full UBsan instrumentation and allow reasonable for development diagnostics.
