Accelerate CI

[Yury-Fridlyand]

Description

Save and restore vcpkg status in GHA cache to accelerate the build. CI run which misses cache takes 23-30 min, CI which hits the cache runs 3-4 min.
Updating dependency versions in src/vcpkg.json file causes cache miss. Cache entries are auto-deleted if not used for more than 2 weeks AFAIK.

Nice finding! But I don't understand how I can use that...
