Please pay attention that I merged several fixes from 4.x to 5.x. Submolules update coming in #1286

[Prasadayus]

@asmorkalov This LNK1120 failure is the known MLAS link bug from the 5.0.0 tag. Also this didn't fail in the previous CI run, when the submodules were still at the 5.1.0 bump.

I can rebase this PR once your submodules update PR #1286 is merged

Also, the Windows ARM CI here runs on GitHub's own Windows ARM runner, not a QDC device.

Ok, I'll trigger CI again as soon as 5.1.0 tag is applied.
