[v9.3.x] Server: Switch from separate server & cli to a unified grafana binary (#62443)

* 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

(cherry picked from commit de99ce139c)

* Build: don't remove grafana-server and grafana-cli binaries from deb and rpm packages (#59890)

* don't remove grafana-server and grafana-cli binaries from /usr/share/grafana/bin in deb and rpm packages
