This PR adds support for the RISC-V
ZkntISA extension (data independent execution time).This extension cannot be enabled by a specific configuration generic. Instead, it is implemented implicitly by certain CPU configuration(s).
Most of the instructions mandated by
Zkntare already implemented in way where the actual data being processed has no impact on the execution time. However, for shift operations this is only true if theFAST_SHIFT_ENtuning option is enabled. Enabling this option will automatically enable theZkntISA extension as well.
