RNG-168: LXM family of random number generators

Add support for generators included in JDK 17:

L32X64Mix
L64X128StarStar
L64X128Mix
L64X256Mix
L64X1024Mix
L128X128Mix
L128X256Mix
L128X1024Mix

Added benchmark for support routines for computing the unsigned long
multiplications in the 128-bit LCG (linear congruential generator).

Added a benchmark for the jump function to allow comparison with the
equivalent base XBG (xor-based generator).

Added a faster carry computation than the method provided in the
reference LXM paper.
