Log Message:
-----------
MdePkg: Add LoongArch64 instance in BaseRngLib
LoongArch64 currently dose not support HW or a standards-compliant RNG.
Read the stable time twice performs an XOR, and then use xorshift
algorithm(from Marsaglia's xorshift generator) to generate a
pseudo-random number.
It's not random enough, but it's definitely better than just using a
timer(BaseRngLibTimerLib).
