cmd_move: allow for all i3 syntax options

This modifies cmd_move to allow for the syntax options allowed by i3.
The following syntaxes are supported:
- `move left|right|up|down [<amount> [px]]`
- `move [--no-auto-back-and-forth] [window|container] [to] workspace
   <name>|next|prev|next_on_output|prev_on_output|current|number <num>`
- `move [window|container] [to] output <name/id>|left|right|up|down`
- `move [window|container] [to] mark <mark>`
- `move workspace to [output] <name/id>|left|right|up|down`
- `move [window|container] [to] [absolute] position <x> [px] <y> [px]`
- `move [window|container] [to] [absolute] position center`
- `move [window|container] [to] position mouse|cursor|pointer`

This also allows retains the following syntax option that is not
supported by i3, but is supported in sway 1.0:
- `move workspace [to] output <name/id>|left|right|up|down`

The changes are:
- `window` and `container` are now optional
- `output` is now optional for `move workspace` when `to` is given

There is also stricter command checking now. If `absolute` or
`--no-auto-back-and-forth` are given for commands that do not support
them, it will be treated as invalid syntax instead of being silently
ignored.
