Bump version to 1.84.2 + Remove x86-64-v2 target

As per this release, we are going to set target build to x86-64-v4 or native. This means, the ILC could possibly support latest intrinsics like AVX2 and AVX512, allowing some code to run better due to wide vectorization.

Some static libraries which utilizes BMI and AVX intrinsics (like ZStandard library) might not run properly on an old machine without AVX or BMI intrinsics support.
