Adding --v1-compatible flag to all previously unsupported command line commands (#6521)

In addition to those commands already supported:

* build
* check
* eval
* fmt
* test

support has been added to the following commands:

* `bench`
* `deps`
* `exec`
* `inspect`
* `parse`
* `run` (command `server` and `REPL`)

Fixes: #6520
