[GHA Build] Factor out osx distro sign, dmg, notarize upload and linux distro upload out of maven build

[BoykoAlex]

Windows distro sign and upload is factored out of maven build and is done in a separate job isnce it requires self-hosted runner.

Factor out OSX sign, dmg, notrization and upload into separate steps in the GHA job. Might even go as far as moving this out into a separate job on the macosx runner then the main distro build would need either linux or macosx runner (rather than just macosx runner)

Factor out Linux distro S3 upload into a separate step out of the maven build.

Consider passing around maven zip via S3 upload rather than GHA upload/download which is considerable slower.
