feat(cmd): mirror (#7004) 
# Which Problems Are Solved

Adds the possibility to mirror an existing database to a new one. 

For that a new command was added `zitadel mirror`. Including it's
subcommands for a more fine grained mirror of the data.

Sub commands:

* `zitadel mirror eventstore`: copies only events and their unique
constraints
* `zitadel mirror system`: mirrors the data of the `system`-schema
*  `zitadel mirror projections`: runs all projections
*  `zitadel mirror auth`: copies auth requests
* `zitadel mirror verify`: counts the amount of rows in the source and
destination database and prints the diff.

The command requires one of the following flags:
* `--system`: copies all instances of the system
* `--instance <instance-id>`, `--instance <comma separated list of
instance ids>`: copies only the defined instances

The command is save to execute multiple times by adding the
`--replace`-flag. This replaces currently existing data except of the
`events`-table

# Additional Changes

A `--for-mirror`-flag was added to `zitadel setup` to prepare the new
database. The flag skips the creation of the first instances and initial
run of projections.

It is now possible to skip the creation of the first instance during
setup by setting `FirstInstance.Skip` to true in the steps
configuration.

# Additional info

It is currently not possible to merge multiple databases. See
https://github.com/zitadel/zitadel/issues/7964 for more details.

It is currently not possible to use files. See
https://github.com/zitadel/zitadel/issues/7966 for more information.
