Server: Switch from separate server & cli to a unified grafana binary (#58286)

* avoid the need for a second bulky binary for grafana-cli

* look for grafana-server in $PATH as well as same directory

* implement unified "grafana" command

* update dockerfiles, fix grafana-cli -v

* update packaging to work with single binary

- add wrapper scripts for grafana and grafana-server
- update and sync package files
- implement --sign flag of build package command
- stop packaging scripts folder, they are not useful for end users
- add support for --configOverrides in server command
- remove unused nfpm.yaml config file

* windows support
