[FEATURE REQ] Add `Parse` and `TryParse` on `ResourceType` type

[ArcturusZhang]

Library name

Azure.Core

Please describe the feature.

The constructor of ResourceType throws exception when the input string does not have a valid format for arm resource type, but it does not give us a method to check if the input type is valid.
Introducing Parse and TryParse method should solve this, just like what we have done for ResourceIdentifier: #32039
