Specifying Make variables via command line takes precedence over and overrides all assignments to it. This causes issues with `GO_FLAGS_EXTRA`, which may be updated to include `-tags` an `-mod` flags, as well as used to pass extra Go flags via command line (e.g., `make GO_FLAGS_EXTRA=-trimpath). Update `Makefile` to update `GO_FLAGS` instead, and leave `GO_FLAGS_EXTRA` unmodified. Move `Makefile` variables intended to be overridden in the command line to dedicated blocks, and add comments to them. Additionally, add fix for new Microsoft Go behavior (starting in go1.25) that requires CGo by default for crypto libraries.

GO_FLAGS_EXTRAbehavior is bugged and cannot be used to pass extra Go flags to the build command.E.g.,
make GO_BUILD_TAGS=rego GO_FLAGS_EXTRA=-trimpath out/delta-snp.tar.gzbuilds the Go binaries with only the-trimpathflag, and not-tags=rego:Specifying Make variables via command line takes precedence over and overrides all assignments to it.
