VLESS inbound: Add option to set default flow

[Jolymmiles]

#4994

Implementation for fr.

How it work.

If defaultFlow isn't set than defaultFlow is "" and all core logic work like in previous versions. But, when we set defaultFlow, then if client don't have flow, then will be set flow from defaultFlow. Its optional parameter.

"settings": {
        "defaultFlow": "xtls-rprx-vision",
        "clients": [
          {
            "id": "c481e5e7-2796-491d-ac55-00e3c1e0acc3",
            "email": "sOoqSgPC2rHuTWRCPLt3"
          }
        ],
        "decryption": "none"
      }

Check before for loop, c.Flow is fixed, one time check is enough.

it has a problem,
"flow": "VLESS.XRV" can override "defaultFlow": "",
but "flow": "" can't override "defaultFlow": "VLESS.XRV"

In short, when defaultFlow is vless.XRV, we cannot set no-flow for a user.

///

We can set "no-flow" as a alias for "".

If we set default flow to xtls-rprx-vision and user flow to ""
Witch will use?

[patterniha]

@Jolymmiles

switch c.Flow {
	case "", vless.XRV, vless.NoFLow:
	default:
		return nil, errors.New(`VLESS "settings.flow" doesn't support "` + c.Flow + `" in this version`)
}

should change to:

switch c.Flow {
    case vless.NoFLow:
        c.Flow =""
	case "", vless.XRV:
	default:
		return nil, errors.New(`VLESS "settings.flow" doesn't support "` + c.Flow + `" in this version`)

now "" means use defaultFlow, doc needs to be updated.

rebased on main

[RPRX]

1. proxy/vless/vless.go 需要将 None 放到 XRV 上面
2. 需要重新 rebase 一下，现在看起来怪怪的
