build: rename swarm deb package to ethereum-swarm; change swarm deb version from 1.8.x to 0.3.x (#16988)

* build: add support for different package and binary names

* build: bump up copyright date

* build: change default PackageName to empty string

* build, internal, swarm: enhance build/release process

* build: hack ethereum-swarm as a "depends" in deb package

* build/ci: remove redundant variables

* build, cmd, mobile, params, swarm: remove VERSION file; rename Version to VersionMeta;

* internal: remove VERSION() method which reads VERSION file

* build: fix VersionFilePath to Version

* Makefile: remove clean_go_build_cache.sh until it works

* Makefile: revert removal of clean_go_build_cache.sh
