[openexr] Fix openexr using unrequested intrinsics

[Neumann-A]

this is way to much typing for small patches

[Neumann-A]

Ok now osx is happy.

[dan-shaw]

Has this change been submitted to upstream?

[Neumann-A]

I informed upstream about it.

[Neumann-A]

upstream has created AcademySoftwareFoundation/openexr#1354 which is the patch added here

[Neumann-A]

@dan-shaw why does this depend on a different pr?

[dan-shaw]

I would prefer if upstream merged first

[Neumann-A]

@MonicaLiu0311 Why should upstream make a new release for such a small and more or less unimportant change? (referring to AcademySoftwareFoundation/openexr#1354 (comment)). Especially since the last release was just last week. I mean if it is CVE fixed here than I would understand that request but this here is just a minor correction for a preprocessor definition correctly allowing AVX which MSVC normally silently ignores/allows (i.e. allowing instructions although the correct arch flag is missing.).

@dan-shaw: I understand that but taking microsoft/vcpkg-docs#35 into account I have to assume you have no confidence in this patch although upstream itself created a PR including the patch and upstream CI being green. I find that kind of funny but its ok ;), just make sure i don't need to remember you to merge this PR if upstream is merged.
