gin TextUnmarshaler support for binding

Adds encoding.TextUnmarshaler checking to support unmarshaling custom non-struct types.
Adds binding.BindUnmarshaler to support unmarshaling custom structs (from the suggestion in #2673)

As of this PR you can support any kind of custom type without breaking support for time.Time and other structs that might implement TextUnmarshaler

Closes #2673 Closes #2631

@kszafran I think I've addressed all your feedback. Mind taking another look?

@thinkerou when you have a chance, could you review/merge/tag another maintainer?

Looks like an essential feature to have. @ssoroka Could you squash your commits as requested per CONTRIBUTING.md? @thinkerou @appleboy Could you check out this when you have time?

Is there anything I can contribute to help get this merged?

To make it work with arrays []uuid.UUID we might add to func setWithProperType:

	case reflect.Array:
		if a, e := trySetCustom(val, value); a || e != nil {
			return e
		}
		return errUnknownType

What are the perf changes for this update?

How much does it slow down binding for other things?

@appleboy @thinkerou @javierprovecho Any update on this?

Again, What is the perf change of this?

Have you done the work to assure it does not slow other things down?

May 19 '23 23:05 duaneking

I don't see any performance impact to this. I've been using this in production for a year and a half at this point. Maybe someone could pick it up, update it, and merge it?

@ssoroka I don't know why I can't review the PR? Can you create a new PR?
