build: enforce SSE2 floating point arithmetics on x86 builds to have consistency
When SSE2 is available, use SSE floating point to get consistent results with x86-64.
Also it is needed for multiple components to prevent non-SSE2 build failures and LTO linking issues.
Fixed LTO build with x86 warnings can be seen here: https://gitlab.com/alpine-mobile/pmaports/-/jobs/3731715028 .
Closes: #8243 (closed)
