Description

Add support for gzip fallback for restore of old cache on windows

Motivation and Context

With compression switching to zstd, old gzip cache might not recover. To support old cache recovery use of gzip is needed. Need to be removed in future

How Has This Been Tested?

Added extra test for this case.
