Implicitly convert value to Some(value) for Option<T> props

[ranile]

Describe the feature you'd like
Implicitly converting value to Some(value) for a prop with type of Option<T>. Consider the following props

struct Props {
    #[prop_or_default]
    pub foo: Option<String>
}

If no prop value is passed for foo then that field will be initialized as None but when a value is to be passed, it must be passed as foo=Some(value). It should be able to be passed as foo=value where value has a type of String (&str) and an implicit conversion should occur which converts to Some(value). This is similar to conversion between String and &str.

Is your feature request related to a problem? Please describe.
Converting to Some when passing value to Option<T> props can get repetitive and can be abstracted away similar to conversion between String and &str.

Describe alternatives you've considered
Doing Some(value) every single time.

Additional context
None, that I can think of.

Questionnaire

• I'm interested in implementing this myself but don't know where to start
• I would like to add this feature
• I don't have time to add this right now, but maybe later
  ...and also my knowledge of proc macros is too limited to efficiently work on this

We already have a transformer for T -> Option<T> (i.e. this should work right now).
Are you getting an error when trying to use it?

It exists? I never knew that and searching in the docs revealed nothing so I never tried it out. I guess this is more of a documentation request than a feature request.

You're right, the documentation on props and their behaviour is very much lacking. I'm hoping to address some of that in #1599.
