Subject: MdePkg: Rename Cache Management Function To Clarify Fence Based Op

There are different ways to manage cache on RISC-V Processors.
One way is to use fence instruction. Another way is to use CPU
specific cache management operation instructions ratified as
per RISC-V ISA specifications to be introduced in future
patches. Current method is fence instruction based, rename the
function accordingly to add that clarity.
