This is a followup of [18932](https://github.com/openjdk/jdk/pull/18932) in 
which all random number generator algorithms have been moved to module 
`java.base` and module `jdk.random` has been removed.

Reliance on `ServiceLoader` in `j.u.r.RandomGeneratorFactory` is no longer 
needed and has been replaced by a (lazily populated) map from algorithm names 
to classes.

Moreover, methods `RandomGeneratorFactory.create(long)` and `create(byte[])` 
now throw an `UnsupportedOperationException` rather than silently falling back 
to the no-arg `create()` in case the underlying algorithm does not support a 
`long` resp. `byte[]` seed.

Tests in tier1-tier3 pass after adaptations on the existing 
`RandomTestCoverage`.
