[Buildbot] Add two new workers for the cross win-to-linux Arm/Aarch64 release builders.

[vvereschaka]

Summary

Added configuration for two new workers:

• as-worker-5 (arm release builders)
• as-worker-6 (aarch64 release builders)

Reconfigure the win-to-linux arm/aarch64 cross release builders to use newly configured workers.

@gkistanova I would like to connect those workers/builders to the staging master at first and switch to the production master later.

LGTM.
