Merge #21592: test: Remove option to make TestChain100Setup non-deterministic

fa6183d7761eef8bb815aa888f0396e92e275f05 test: Remove option to make TestChain100Setup non-deterministic (MarcoFalke)
fa732bccb3cf9bc2cdc444975286df0e799917a2 test: Use compressed keys in TestChain100Setup (MarcoFalke)

Pull request description:
