Recognize UUID as a string type

**Is your feature request related to a problem? Please describe.**

I can't gracefully populate a UUID-type field when using Eino Dev，because it is recognized as an int type.

**Describe the solution you'd like**

Can we add some tag controllers?

**Describe alternatives you've considered**
like:

```go
type Input struct {
Id uuid.UUID `json:"customer_id,string"`
}
```

or:

```go
type Input struct {
Id uuid.UUID `json:"customer_id" eino:"string"`
}
```

Start by locating the Eino Dev type-recognition and tag-handling logic that classifies uuid.UUID, then compare it with the existing int and string handling. The issue's examples show the intended inputs; done means UUID fields can be populated as strings through the supported tag or type behavior.
