Use CMS_USE_AVX2 instead of CMS_USE_AVX

[smuzaffar]

Fixes #33267

SSEVec.h has code for AVX2 and does not work when build for avx e.g sandybridge ( see #33267). This PR proposes to define CMS_USE_AVX2 instead of CMS_USE_AVX when __AVX2__ is available.

This change should not have any effects of normal cmssw builds as we build with -msse3 however this should fix the SKYLAKEAVX512 IBs which are now build for sandybridge,haswell,skylake-avx512
