opencv: assorted fixes (#15971)

Browse source 
* opencv: assorted fixes

1. depends on blas when +lapack
2. set cuda nvcc flags for cuda_arch
3. let cuda/contrib builds work
4. depends on hdf5 when cuda/contrib
5. depends on ant when +java
6. allow protobuf version to be different
7. let opencv recompile it's protoc files.

* ant is a build-time dependency

* register +cuda~contrib as impossible.
