Meta could have Valuer/FormattedValuer/Setter that pass/expect value instead of record

[gstvg]

Supose this from docs; The valuer cant be used on other resources, "admins" for example.

user.Meta(&admin.Meta{Name: "Password",
    Type:   "password",
    Valuer: func(interface{}, *qor.Context) interface{} { return "" },
    Setter: func(record interface{}, metaValue *resource.MetaValue, context *qor.Context) {
        if newPassword := utils.ToString(metaValue.Value); newPassword != "" {
            bcryptPassword, _ := bcrypt.GenerateFromPassword([]byte(newPassword), bcrypt.DefaultCost)
            record.(*models.User).EncryptedPassword = string(bcryptPassword)
        }
    },
})

Passing value on Setter would allow to do this:

type Password string

type Admin struct {
    ....
    VeryEncryptedPassword Password
    OldVeryEncryptedPassword Password
}

type User struct {
     .....
     EncryptedPassword Password
    OldEncryptedPassword Password
}

func (p Password) ConfigureQorMeta(metaor resource.Metaor) {
     meta := metaor.(*admin.Meta)
     meta.SetValuer(func(interface{}, *qor.Context) interface{} { return "" })
     meta.SetSetter(func(value interface{}, metaValue *resource.MetaValue, context *qor.Context) {
        if newPassword := utils.ToString(metaValue.Value); newPassword != "" {
            bcryptPassword, _ := bcrypt.GenerateFromPassword([]byte(newPassword), bcrypt.DefaultCost)
            value = &Password(bcryptPassword)
        }
    }
}

Note different struct field names and multiple fields with Password type, disallowing using reflection searching for a specifig field name and/or type. (On this specific example, on the Setter, we could change metaValue and call the default Setter(like rich editor do), but this cant be done on Valuer/FormattedValuer)
